Limitations
- storeBackup can backup normal files, directories, symbolic links
and named pipes. You can backup other file types only with option
cpIsGnu (and if gnu cp is installed on your system).
- The permissions in the backup tree(s) are equal to the
permissions in the original directory. Under special rare conditions
it is possible that a user cannot read one ore more of own his/her
files in the backup because files are shared using hard links. With
the restore tool - storeBackupRecover.pl - everything is
restored with the original permissions.
- storeBackup uses hard links to save disk space. GNU/Linux with
ext2 file system supports up to 32000, reiserfs up to 64535 hard
links when you use a 32 bit operating system. If storeBackup needs
more hard links, it will store a new (compressed) copy of the
file. If you use ext2 for the backup, you have to reserve enough
(static) inodes! (You will need one inode for each different file in
the backup, not for every single hard link.)
- Changing the compression program is not supported up to now. In
a backup (``backupDir'') you should use the same compression program.
