Hi all - Likely a stupid question, but is it safe to remove the --ignore-times rsync option in the BackupPC config.pl file? When I've done rsync backups before with simple scripts, I've never used that option, and have yet to land in hot water because of it. While in an ideal world we'd check the file contents every time, it seems pretty unlikely to bear any fruity 99.999% of the time.
The reason I'm considering axing this option is that I'm setting up a remote backup server backing up about 1TB of data. I'm concerned that running a full backup in the future will take days to complete, when really few files changed (initial full backup was done on the local network). The remote network link is about 1Mbit/sec, and there is other data going over this link, so really we'll have about 500Kbit for backup, or less. This also ties in with the discussion "Full backup bandwidth reduction". If BackupPC really is bandwidth efficient during the full backup, I could leave --ignore-times on, but so far I'm not convinced. I don't have any solid data yet, though. I guess we'll see soon. I'm also concerned about disk utilization as the backup server has only about 1TB of disk space and the backup set compressed is around 500GB. If subsequent full backups will take another 500GB, even temporarily, we'll be in trouble. Sounds like this shouldn't be the case, but I'm not convinced yet on this either based on what I've seen so far. I've read through the config.pl file and there is an option (marked useless) for doing "filled" incrementals, which would seem to do what we want. Just do one full backup, then incrementals after that... Of course if all the files end up matching what's in the pool on a full backup, everything should be hunky dory without using filled incrementals. Thanks in advance for your thoughts!
