Storetape & whichtape README

Storetape and whichtape are tools I cobbled together a couple of years
ago to facilitiate backup restores.   Rather than have to mount a bunch
of incremental tapes to find out which one a particular file was on,
these shell scripts impliment a simple data base which contains the table
of contents of each backup tape.

The data base is created by storetape and access by whichtape.
The data files are compressed to save disk space and since they should
not be accessed very often, so the compression/decompression time to
disk space tradeoff is reasonable.

For incremental dumps, a 'restore t' was done on each backup tape right
after the dump was done.  This table of contents is fed to storetape.
This also verifies that the tape just written can be read, at least up
to the directory information.

For level 0 dumps which span several tape reels, this method is impractical.
Instead 'ncheck -i' is used to generate a list of file names.
Any program or method which generates a list of names in a file tree
would provide proper input for storetape.

These scripts leave their database in the current directory.
Customization of that is left to the installer.
