Spans staged data among multiple discs
This is the Cedar Backup span tool. It is intended for use by people who stage more data than can fit on a single disc. It allows a user to split staged data among more than one disc. It can't be an extension because it requires user input when switching media.
Most configuration is taken from the Cedar Backup configuration file, specifically the store section. A few pieces of configuration are taken directly from the user.Author: Kenneth J. Pronovici <pronovic@ieee.org>

Runs a consistency check against media in the backup device. The function mounts the device at a temporary mount point in the working directory, and then compares the passed-in file list's digest map with the one generated from the disc. The two lists should be identical. If no exceptions are thrown, there were no problems with the consistency check.
Warning: The implementation of this function is very UNIX-specific. |
