[Duplicity-talk] Missing full backup...

[Carlos Chavez]

    I seem to be having a problem.  I have several servers backing up 
to a single server.  All except one are working perfectly and I have 
been able to restore files from all of them.  All servers do a FULL 
backup on Sunday and incremental backups the rest of the week. One of 
the servers (used for email) misses the FULL backup on Sunday some of 
the times and keeps going with incremental backups.  Here is the listing:

-------------------------
No orphaned or incomplete backup sets found.

    I have no idea why this particular server will sometimes fail to do 
the FULL backup on Sunday.  There seem to be two incremental backups for 
Sunday.  I run the incremental backup from cron.daily and the full 
backup from cron.weekly.  All servers have exactly the same cron jobs.  
We are using Duplicity 0.6.13 which is the latest version we can compile 
on out CentOS 5.10 servers.
