Hello. Recently I've started using BackupPC to backup my file server and am seeing some things that just don't quite make much sense. Lately backups have been taking quite some time, in fact the current one started on 2/16 @ 11pm and is still running. I do have a lot of data, around 330G, but not a whole lot changes on a daily basis.
Here are my latest backups with the times: Compression performance for files already in the pool and newly compressed files. Existing Files New Files Backup# Type Comp Level Size/MB Comp/MB Comp Size/MB Comp/MB Comp 0 full 3 78446.6 45871.8 41.5% 258032.2 155715.6 39.7% 2 incr 3 276482.0 165123.8 40.3% 143.0 70.3 50.8% 3 incr 3 900.7 530.7 41.1% 964.7 469.5 51.3% 4 incr 3 113.5 2.7 97.6% 218.0 30.8 85.9% 5 incr 3 73.4 6.1 91.7% 194.8 32.2 83.5% 6 incr 3 304.3 172.2 43.4% 1735.9 944.0 45.6% 7 incr 3 275955.3 165019.1 40.2% 1337.0 658.0 50.8% 8 incr 3 520.4 249.4 52.1% 672.7 282.5 58.0% 9 incr 3 502.9 243.5 51.6% 587.6 264.1 55.1% 10 incr 3 116.8 3.7 96.8% 201.5 24.3 88.0% 11 incr 3 14.0 3.0 78.7% 244.3 32.8 86.6% 12 incr 3 127.1 5.3 95.9% 82.2 22.3 72.8% 13 incr 3 276989.9 165643.4 40.2% 329.3 40.7 87.7% 14 incr 3 275957.9 165146.0 40.2% 1503.5 615.1 59.1% My question is, why did backups 13 and 14 backup all that data? Same with 2 and 7 for that matter. Here's the times for the first few backups to give you an idea of the time it's taking: Backup# Type Filled Level Start Date Duration/mins Age/days Server Backup Path 0 full yes 0 2/9 07:29 1767.6 9.0 /backup/BackupPC/pc/fileserver/0 2 incr no 1 2/10 23:59 1124.8 7.3 /backup/BackupPC/pc/fileserver/2 3 incr no 3 2/11 19:00 68.3 6.5 /backup/BackupPC/pc/fileserver/3 4 incr no 4 2/12 01:00 73.6 6.3 /backup/BackupPC/pc/fileserver/4 5 incr no 5 2/12 07:00 73.9 6.0 /backup/BackupPC/pc/fileserver/5 6 incr no 6 2/12 13:00 102.5 5.8 /backup/BackupPC/pc/fileserver/6 7 incr no 1 2/12 19:00 1097.0 5.5 /backup/BackupPC/pc/fileserver/7 Below is my config. I'm still messing with the IncrLevels and have a super short period just to get some increments and all that going. $Conf{PingMaxMsec} = '200'; $Conf{RsyncShareName} = [ '/', '/data/secondary', '/boot' ]; $Conf{BackupFilesExclude} = { '*' => [ '/dev', '/mnt', '/proc', '/sys', '/tmp', '/var/named/chroot/proc' ] }; $Conf{BlackoutPeriods} = []; $Conf{IncrKeepCnt} = '12'; $Conf{IncrLevels} = [ '1', '2', '3', '4', '5', '6' ]; $Conf{IncrPeriod} = '0.24'; $Conf{RsyncArgs} = [ '--numeric-ids', '--perms', '--owner', '--group', '-D', '--links', '--hard-links', '--times', '--block-size=2048', '--recursive' ]; I also have logging set to 1 and when looking at the XferLOG I do see all the files, but I'm seeing a lot of "create d" I'm not sure what the column should be when it is transferring a file. Any ideas as to what may be going on? After the initial backup, I would expect each increment to only take a short amount of time. Thanks in advance for any insight!
