For what it's worth, Bacula copes quite happily with one fileset here that's just under 1Tb and just over 5 million files - both on backup and on individual file restore. I'm backing up just under 20Tb and about 20 million files overall, with a runtime of abour 20 hours per Tb on full backup (spooling+flushing) Because of the way Bacula spools and flushes, I can backup 2 1Tb filesystems in the same period on the same tape drive. There's no net gain from trying 3 concurrent full backups on one tape drive even though the drive spends a lot of time idle with 2, as the source RAID arrays can't keep up with that much load (they're great at streaming, but slow down if required to seek a lot - as happens when reading 2 filesystems off the same device). This may change as I add more arrays... ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
