It can be used on any Amiga model, providing you have Kickstart V37 or higher, and at least 1 Mb of memory. ABackup has all the features you might expect from such a program: - Both full and selective backup and restore operations (you can select the files by name, by date, by protection bits, but also one by one) - Backup to floppy disks, to partitions (for example a SyQuest cartrige) or to an archive file. Optional data compression, data encryption, verification, and archive bit setting. - Restore to any directory, with or without restoring the original directory tree, and handling of already existing files. Optional date and empty directories restore. - Backup of non-AmigaDOS partitions (PC, Mac, UNIX, ...) - Optional report file for all operations - Full Intuition interface, AmigaGuide documentation. However, ABackup is not just one more backup program. This program also provides unusual features, like: - transparent support of High Density floppy disks. Cyclic utilisation of several disks drives. Supports mixing of Double Density and High Density floppy disks. Transparent support of the "diskspare.device". - Asynchronous writes for maximal backup speed - Data compression can be performed by the "xpk.library" or an external program. Automatic exclusion of files already compressed. - Allows full operation automatization : you can, for example, start a backup just with a double-click over an icon. - Lots of controls, in order to avoid data loss due to handling errors. - Supports of the "MultiUserFileSystem" : access rights and owner are automatically backed up. When restoring files to a partition which is managed by this filesystem, theses informations will be automatically restored. @endnode @node InfoLegales "Legal information" The "xpk.library" library is (C) by U. Dominik Mueller, Bryan Ford, Christian Schneider, and the others XPK authors. The "diskspare.device" device is (C) by Klaus Deppisch.

Once ABackup has been loaded and setup, the program automatically loads the directory tree (or the archive catalog) and does the file selection. Then, the @{" Monitor window " Link "MonitorWin"} appears, and the specified operation begins. @endnode @node StdShell "Interactive with Shell interface" This mode is selected when you start ABackup from a Shell command line, specifying at least the operation to perform (BACKUP, RESTORE or VERIFY arguments) and the operation source (FROM argument). The program will not open any Intuition window (except for the requests) but will rather print messages into the Shell window. Once ABackup has been loaded and setup, the program automatically loads the directory tree (or the archive catalog) and does the file selection. Then, the specified operation begins and messages, like those usually displayed on the @{" Monitor window " Link "MonitorWin"}, appear on the Shell window. @endnode @node AutoShell "Automatic with Shell interface" This mode is selected like the @{" Interactive with Shell interface " Link "StdShell"} mode, but with the additionnal QUIET argument. In this case, ABackup doesn't make any request nor any display (except error messages), so it is suggested to ask for a full operation report. Once ABackup has been loaded and setup, the program automatically loads the directory tree (or the archive catalog) and does the file selection. Then, the specified operation begins. @endnode @node Arguments "Arguments" The list of possible ABackup arguments is shown below. For each argument, the first line shows the Shell syntax, while the second one shows the Tool Types syntax. FROM/K source FROM=source Specifies the name of the source directory or volume (backup), or the source archive (restore/verify). In order to backup several volumes at the same time, specify the volume names separated by a comma (e.g. "SYS:,Work:"). TO/K destination TO=destination Specifies the name of the destination archive (backup), or the directory to restore to (restore). B=BACKUP/S MODE=BACKUP Begins a backup operation, in automatic mode. R=RESTORE/S MODE=RESTORE Begins a restore operation, in automatic mode. V=VERIFY/S MODE=VERIFY Begins a verify operation, in automatic mode. SE=SELECT/K ARC|file SELECT=ARC|file Specifies the name of the selection file to use (see @{" Selection recording " Link "EnrSelection"}). By default, in automatic mode, all the files are selected. The "ARC" keyword is an easy way to select all the files with the archive bit cleared, whithout having to create a selection file. RP=REPORT/K file REPORT=file Specifies the name of the report file. IM=IMAGE/S IMAGE This toggle activates the "image" backup, which allows to backup non-AmigaDOS disk partitions. PRF=PREFS/K file PREFS=file Specifies the name of the Preferences file to use. CAT=CATALOG/K file CATALOG=file Specifies the name of the archive catalog file (restore/verify). Useful only if the "Use catalog file" option has been activated. SFX=ECSUFFIX/K .suffix ECSUFFIX=.suffix Specifies the suffix added by the external compression program. For example, if you want to use the LZX program, you must specify the ".lzx" value for this argument. QUIET/S This toggle activates the @{" Automatic with Shell interface " Link "AutoShell"} mode. HELPPATH=directory Specifies the name of the online help directory. Default value is "HELP:language", where language is the prefered language, as specified in the system Preferences. PREFSPATH=directory Specifies the name of the Preferences program directory. Default value is "SYS:Prefs". @endnode @node MainWin "Main window" The main window allows selection of the operation to perform: Backup files and dirs To backup a directory, or one (or more) logical volume, by archiving all the files in this directory or this volume(s). Once you will have selected the source directory or volume, ABackup will load the list of the corresponding files, and display the @{" Selection window " Link "SelectionWin"}, to let you select the files to backup. Any file or directory which comment begins with the "SKIPME" keyword will be ignored when scanning the directory tree : this feature avoids wasting lots of time loading the contents of a big directory you never backup. Backup partitions To backup one or more physical volumes, by archiving every cylinder of this volume(s). ABackup will display the @{" Selection window " Link "SelectionWin"}, to let you select the partitions to backup. CAUTION ! Restoring such partitions will be possible only if their characteristics have not changed : for exemple, the size and location of the partition must be the same as those backed up. Take note that ABackup can't format the target drive : if you need to restore a partition to a new disk drive, you must first low-level format it. Restore To restore data previously backed up. ABackup will display the @{" Archive selection window " Link "ArchiveWin"}, to let you select the archive to restore. Verify To verify an archive. This means at least integrity checking, but you can also ask to compare backed up data with original data. In this last case, ABackup will perform integrity checking even if a comparison is not possible (original file not found, etc...) ABackup will display the @{" Archive selection window " Link "ArchiveWin"}, to let you select the archive to verify. Rebuild catalog This function is useful when an archive file is damaged, or if you lose the last floppy disk of a backup set : it allow to rebuild the archive catalog, which is required to restore data. Take note that this function is not supposed to recover any error that may occur, and is not intended for inexperienced users. If the damaged archive is an archive file, you must first check that the first header block is at a block boundary, that is at a address multiple of 512 (you may use the "TYPE archive HEX" command for this, the first and the third long word of the header blocks are set to "#0000"). If the damaged archive is on floppy disks, you must give the disks in increasing order of disk numbers. This function works even if some disks are missing. ABackup will display the @{" Archive selection window " Link "ArchiveWin"}, to let you select the archive for which the catalog is to rebuild. Preferences To call the external configuration program See also @{" Application window " Link "AppWindow"}. @endnode @node SelectionWin "Selection window" This window shows the list of files or partitions, so that you can select which ones are to backup, restore, or verify. It is made of an upper part, containing selection gadgets, and a lower part, in which is displayed the list of the files or partitions. You can scroll this list, using the scroller at the right of the window. You can print the currently displayed list, using the "Print current list" item in the "Project" menu. When selecting files to backup, you can add a new volume or directory to the current list, using either the "Add directory" item in the "Project" menu or the @{" Application window " Link "AppWindow"}. In order to have an estimation of the number of disks and of the time required for the backup, you can use the "Estimate" item in the "Project" menu. The "Files:" and "Size:" fields respectively show the number of selected files or partitions, and the total size of the selected objects. The "Directory:" field shows the name of the directory containing the currently displayed files. To go down in the directory tree, just click on a directory name : the contents of this directory will be displayed (except if this directory is empty). The "Root" and "Parent" gadgets allow to go up in the directory tree, respectively to the root directory and to the parent directory of the current directory. If you click on a file, empty directory, or partition's name, you will toggle the state of this entry : if it was selected, it will be unselected, and if it was not selected, it will be selected. To toggle all the contents of a non-empty directory, you just have to hold down the SHIFT key, while clicking on the directory's name. You can move the mouse without releasing the left button, in order to "drag-select" or "drag-unselected" the other files, directories, or partitions. If you double-click on a file's name, ABackup will try to call a viewing program, depending on the file's type. A requester will allow you to confirm the viewing request and, if necessary, to modify the name of the program to call. If you double-click on a partition's name, ABackup will display some information about this partition (unit number, number of blocks per track, etc...). The selection gadgets are: Filter Tells if the other selection gadgets will add ("Include") or remove ("Exclude") files or partitions from the selection list. Recursive If activated, any selection action will be recursively applied to any files or directories, contained in the sub-directories of the current directory. All Include or exclude all the files or partitions. Reverse Toggle all the selection : any selected file or partition is unselected, and any unselected file or partition become selected. By name Include or exclude all the files or partitions matching a name ("ram:foo" for example) or a pattern ("#?.info" for example). ABackup recognize the same patterns as AmigaDOS (refer to your AmigaDOS manual for more information). A requester will allow you to enter the name or the pattern. Two gadgets allow you to find files or partitions that match ("Match") or that don't match ("No Match") the given name or pattern. By date Include or exclude files depending on their last modification date and/or time. A requester will allow you to enter the date (in "DD-MM-YY" or "DD-MMM-YY" format) and/or the time ("HH:MM:SS" format). If you only specify a date, the time will be assumed to be "00:00:00". If you only specify a time, the date will be assumed to be today's date. Two gadgets allow you to find files modified before ("Before") or after ("After") the specified date. By bits Include or exclude files depending on their protection bits. A requester will allow you to specify, for each protection bit, if you want it to be set ("+" character in the corresponding gadget), cleared ("-" character in the corresponding gadget), or if you don't want to test it (empty gadget). At the bottom of the window, three gadgets allow (from left to right): - to start the operation (backup, restore or verify). ABackup will display the @{" Monitor window " Link "MonitorWin"}. - to call the external configuration program - to go back to the @{" Main window " Link "MainWin"}. Last, the "Selection" menu allow to record a selection, in order to recall it later. See @{" Selection recording " Link "EnrSelection"} for more information. @endnode @node MonitorWin "Monitor window" This window allows you to follow the process of the current operation (backup, restore, etc...). It is made of an upper part, with eleven information fields, and a lower part in which messages are displayed. The information fields are: Saved/Restored/Verified/Read Number of files or partitions processed (left), number of bytes processed (right). The gauge at the right of the window shows the percentage of files or partitions processed on the total number of selected objects. Left Number of files or partitions not yet processed (left), number of bytes not yet processed (right). The gauge at the right of the window shows the percentage of files or partitions not yet processed on the total number of selected objects. Disk Number of the current floppy disk (left). Duration of the operation (right). Compression Compression ratio. Destination/Source Archive name. The gauge at the right of the window shows the current position on the target (write) or source (read) volume. At the bottom of the window, the "Pause" gadget allows you to pause the operation. Click a second time on this gadget to resume. The "Abort" gadget allows you to definitively abort the operation (you will be asked for confirmation). The name of the optional report file is displayed between these two gadgets. Once the operation finished, ABackup will ask you if you want to go back to the @{" Main window " Link "MainWin"}. If you answer "no", the program will go back to the @{" Selection window " Link "SelectionWin"}. @endnode @node LoadTreeWin "Loading window" This window appears while ABackup is scanning the contents of a directory or a volume, or loading the catalog of an archive. It allows your to follow the processing and, if necessary, to abort it by clicking on the "Abort" gadget : ABackup will return to the @{" Main window " Link "MainWin"}. Once the loading finished, ABackup will display the @{" Selection window " Link "SelectionWin"}, so you can select the files or partitions to process. If you have asked for a "Verify" operation, note that a Preferences option allows you to skip the selection and to always verify all the archive. @endnode @node InfoWin "Information window" This window appears when ABackup is about to load the catalog of an archive. It displays some information saved during the backup : Source Name of the source directory(ies) or volume(s). Files Number of files in the archive. Bytes Number of data bytes in the archive. Date Backup date. Time Backup time. Compression Compression method used for the backup. Comment Optionnal comment specified during the backup. To continue the operation, click on the "Continue" gadget : ABackup will display the @{" Loading window " Link "LoadTreeWin"}. To cancel and go back to the @{" Main window " Link "MainWin"}, click on the "Abort" gadget. @endnode @node ArchiveWin "Archive selection window" This window is like the one used by the Preferences program. It is made of: - a cyclic gadget that lets you select the archive type (device, file, tape) - two lists that let you select the units to use, if the archive type is set to "Device". The list on the left shows all the connected units, the one on the right shows the units to use. To transfer a unit from one list to another, just click on it's name in the list. - a string gadget, and a request calling button, that lets you select the name of the archive file, if the archive type is set to "File". - a gadget that allows you to ask to load the archive catalog from a file, instead of loading it from the archive itself. To validate the request, click on the "Ok" gadget : ABackup will then display the @{" Information window " Link "InfoWin"}, if you have asked for a restore or a verify operation. If you asked for a catalog rebuilding, ABackup will display the @{" Monitor window " Link "MonitorWin"}, and will start to read the archive. Once the archive will have been read entirely, ABackup will create an archive catalogue file. To use this catalog, activate the "Use catalog file" option. @endnode @node EnrSelection "Selection recording" ABackup has the capability of recording a file selection so that you can recall it later. This can be useful if you frequently use the same selections (for example all the files with the archive bit cleared) but also when using one the automatic mode: you can specify the name of a selection file as an @{" Arguments " Link "Arguments"}. The recording process records the selection actions themselves, and not the name of the selected files (assuming you don't select files or directories by clicking on their names in the list). This way, you can apply this selection to any source directory. Also, if new files are created, they will be automatically taken in account. In order to record a selection, choose the "Record" item in the "Selection" menu, on the @{" Selection window " Link "SelectionWin"}. Once you will have specified the name of the selection file, ABackup will record all your selection actions. Once you have finished, select the "Save" or "Abort" item in the "Selection" menu, depending on whether you want to keep this selection or to cancel the recording. To recall a selection, select the "Load" item in the "Selection" menu. A file requester will be displayed, allowing you to specify the selection file you want use. Then the file will be loaded, and ABackup will execute the selection actions it contains. Selections are recorded as text files, in a directory specified in the Preferences. Here is the description of the selection language used by ABackup, which will allow you to create or modify a selection file as you like, by means of your usual text editor. CD : Go back to the root directory CD / Go back to the parent directory CD "dir" Go down into the given sub-directory INVERT Reverse the selection RECURS {YES|NO} Set the recursivity flag INCLUDE ALL EXCLUDE ALL Include/exclude all the files INCLUDE "name" EXCLUDE "name" Include/exclude the given file or directory INCLUDE NAME "name or pattern" {MATCH|NOMATCH} EXCLUDE NAME "name or pattern" {MATCH|NOMATCH} Include/exclude using the given name or pattern INCLUDE DATE "date and/or time" {UPTO|SINCE} EXCLUDE DATE "date and/or time" {UPTO|SINCE} Include/exclude using the given date and/or time INCLUDE BITS mask value EXCLUDE BITS mask value Include/exclude using protection bits (files for which "bits AND mask = value") Here is an example of selection file: RECURS YES ; back to the root ! CD : ; clears any previous selection EXCLUDE ALL ; include all files with archive bit cleared INCLUDE BITS "0x10 0x00" ; exclude all ".o" files EXCLUDE NAME "#?.o" MATCH Note that empty lines and lines starting by a ";" character are ignored. Also note that ABackup automatically stores the state of the recursivity indicator at the beginning of your selection record: if you take a look at the created files, you'll see that they all begin with a "RECURS" command. If you want to be sure to clear a previous selection, it is recommended to start all your selections by clicking on the "Root" gadget and then excluding all the files of the selection. @endnode @node Compatibilite "Compatibility with the previous versions" ABackup has been entirely re-written for this version. Archives created by the previous versions of the program are supported as follow: v1.00-v2.01 you must rebuild the archive catalog v2.10-v2.43 directly supported v3.00-v3.12 NOT SUPPORTED v4.00-v4.09 directly supported Archives crypted by a previous version are NOT supported, whatever version you used for the backup. @endnode @node AppWindow "Application window" When you run ABackup on the Workbench screen, the program's window is automatically set as an "Application Window". If you run ABackup on a public or custom screen, an "Application Icon" is automatically opened on the Workbench screen. This allows you to drop the following icons: Preferences file icon Accepted on the @{" Main window " Link "MainWin"} and the @{" Selection window " Link "SelectionWin"}. The file will immediatly be loaded, and the new parameters taken in account. Archive file or volume Accepted only on the @{" Main window " Link "MainWin"}. The corresponding archive will immediatly be scanned for a restore operation. Directory(ies) or AmigaDOS volume(s) icon(s) Accepted on the @{" Main window " Link "MainWin"}, or the @{" Selection window " Link "SelectionWin"} if the current operation is a backup. The list of the files contained in the corresponding directory(ies) or volume(s) will immediatly be loaded and added to the list of the files to backup. Selection file icon Accepted only on the @{" Selection window " Link "SelectionWin"}. The file will immediatly be loaded, and the selection executed as if you had selected the file with the "Open" item of the "Selection" menu. A double-click on the Application Icon will bring to the front the screen used by ABackup. @endnode @node Merci "Thanks" A lot of people have helped us, directly or not, to finish this project.

For archives created by v5.10 or higher, the generated catalog will be good up to 64 sub-directory levels, and 256 sub-directories per level. Things will also be better (but not perfect) for previous archive formats. - About two times faster when reading archives (restore/verify operations) - Filename sorting algoritm changed (now takes less than two seconds to sort a 3000 files directory, instead of more than one hour) - Selected/processed/left sizes have now a decimal (i.e. 2.6 Mb instead of 2 Mb) - Input/output buffer for streamer access can be allocated in FAST memory now. - A few bugs fixed in old archive format support - Automatic splitting of large files will now be correct even if the temporary directory is not on RAM: - Windows where too high on a Custom screen, so the screen's menu bar could disappear in some cases. - Added missing "__stackext" directive on two recursive functions v5.11, 03-Feb-96, 112152 bytes - No longer crashes when it have to switch to another disk drive to write the archive catalog - The "Print current list" item used to send the output to the "Ram:Toto" file, instead of the printer @endnode @node FAQ "Frequently Asked Questions" Q:Even though I am a registered user, I still have to reply to the "About" startup request. A:There is no special "registered" version of the program, nor "keyfile" sytem. Everybody has this request, even ABackup authors. Of course, it is not displayed in automatic modes. Q:I've tried to use LZX, with external compression, but it doesn't work. All the files are "Stored", and lots of ".lzx" files are left in the temporary directory. A:If the external compression program adds a suffix to filenames (LZX adds ".lzx"), you must use the ECSUFFIX argument to tell ABackup which suffix is added. Q:At the end of a backup, I had a requester "CAUTION ! Some cylinders on the target drive were defectives !". I thought ABackup could handle this kind of problem, so I would not have to restart the backup again. R:This kind of error is handled by ABackup, which simply marks the bad cylinders as "unusuable", and try to write on the next cylinder. This message is only here to suggest you to perform a verify operation, to make sure the backup is correct (some write errors might have not been detected). @endbase @endnode
