*We have been running rdiff-backup via a cron script (follows) for the last
few months against 3 systems with no problem. The backup directory is
rotated each week, and last night the initial (full) backup apparently
failed.*
*BACKUP SCRIPT:*
#!/bin/sh
logfile=/var/log/rdiff-backup.log
export update=$(date +'%H%M%S')
/bin/date +'%H%M%S' >> /mySQLbackup/rdiff-backup-time.log
#echo "$update" >> /var/log/rdiff-backup.log
exec >> $logfile 2>&1
export WEEK=$(date +'%V')
### The WEEK var is to recycle the backup each week.
### The time wrapper captures the Elapsed time, User time, CPU time, and
the percentage of CPU time used by the process.

Fatal Error: Bad rdiff-backup-data dir on destination side
The rdiff-backup data directory
/mySQLbackup/VREI01/13-system-rdiff-backup/rdiff-backup-data
exists, but we cannot find a valid current_mirror marker. You can
avoid this message by removing the rdiff-backup-data directory;
however any data in it will be lost.
Probably this error was caused because the first rdiff-backup session
into a new directory failed. If this is the case it is safe to delete
the rdiff-backup-data directory because there is no important
information in it.

*We then attempted to rm the problem directory so the backup would
regenerate. The same error was generated.
We then stopped cron and waited until the rdiff-backup activities closed,
removed the directory again, and started cron. The next attempt also
failed.
Cron was stopped again, the script modified to place the backup in a
different directory, thinking that would assure us that there was nothing
to be seen to generate the error. The first pass to that directory also
errored, but then appeared to recover. Is there something dropped on the
data source system that rdiff-backup would detect as a "Found interrupted
initial backup."* *Any other ideas of what the problem could be?*
