Error (FFFFFFFF) occurred while saving a backup of the iPrint Manager database file

Periodically, the following message will be seen in /var/log/messages :

  Error (FFFFFFFF) occurred while saving a backup of the iPrint Manager database file

Performing a manual backup (or "Defrag Database") via

• go to http://ip_or_dns_of_iprint_server/PSMStatus
  
• Login
• Advanced iPrint Manager
• iPrint Manager Internal (under interface column)
• select "Backup Database" or "Defrag Database"
  

The amount of time to backup and/or defrag the database will be related to the number of printers in the print manager and the volume/number of print jobs submitted.  On a server with 10 printers and few print jobs, a backup or defrag should take less than 5 seconds.  If you have hundreds of printers, and users constantly printing to them -- it is advisable to wait for a low point in traffic before backing up or defragging the database.

If backup or defrag still doesn't work, you may have a damaged database and need to restore or recreate the print manager database.  Detailed information on database restoration can be found in: KB 3006957 - Restore Linux Print Manager database in disaster recovery situation.
