No. The difference between full and incremental backup (using rsync) is just that with full backup, some (configurabel) percentage of the files is checked even though it looks unaltered, so corruptions in BackupPCs pool will be detected. Therefore, the full only needs slightly more bandwidth, but a lot more I/O and CPU on client and server. > Our big issue here is retention - we have to keep backed up files > indefinitely, can backuppc maintain a continually growing catalog of > indefintely retained files? Yes, it can. Just set the appropiate configuration properties to insanely high values. The real question is: Will your file system cope with all the files? And: Are you prepared to backup the BackupPC data to some offsite storage (Tape, swappable disks etc.)? Do you have an estimate of the volume of data? Hm. If you really want to keep indefinitely, you could use the following strategy: - set up BackupPC with some swappable storage (like eSATA disks, possibly in RAID1 for security) - let BackupPC fill the storage - if you reach 95%, remove the storage, replace by new disks and start from scratch (bonus: take one backup from each host as a starting point to get the pool filled initially so you spare the file transfer over WAN) I suppose, you're talking about lots of Gigabytes here. Managing Terabytes of storage is still a challenge since disks didn't get a lot faster during the last years (as opposed to CPU and memory). It needs careful planning (RAID, volume management, file system, upgrade paths). > Of course, we would probably need to install a 64-bit database server.... There's no database involved in BackupPC. It's storage is pure file system.
