Hello Jim, here I have the logs from two different hosts, each backed up with v3 and v4. Unfortunately, both hosts have been set up in BackupPC for a while, so they are not completely fresh backups. However, I don't think that should make a difference. You can see that despite identical numbers of files, the backups have significant differences in size.
HOST A v3 2022-12-12 10:15:15 full backup started for directory / (baseline backup #4521) 2022-12-12 10:17:31 full backup 4522 complete, 75368 files, 4031524511 bytes, 1 xferErrs (0 bad files, 0 bad shares, 1 other) Remote[2]: file has vanished: "/var/spool/exim4/input/1p4eu4-0002rf-1f-D" v4 2022-12-12 10:15:28 full backup started for directory / 2022-12-12 10:17:19 full backup 38 complete, 75368 files, 5279057447 bytes, 0 xferErrs (0 bad files, 0 bad shares, 0 other) HOST B v3 2022-12-05 20:00:07 full backup started for directory / (baseline backup #1612) 2022-12-05 22:10:15 full backup 1613 complete, 554199 files, 151127936698 bytes, 2 xferErrs (0 bad files, 0 bad shares, 2 other) Remote[2]: file has vanished: "/mnt/system/tmp/cron-apt.klojST/initlog" Remote[2]: file has vanished: "/tmp/cron-apt.klojST/initlog" v4 2022-12-05 20:16:24 incr backup started for directory / 2022-12-05 20:49:47 incr backup 13 complete, 554199 files, 231723535659 bytes, 0 xferErrs (0 bad files, 0 bad shares, 0 other) The output of the XferLOG seems to be very different between v3 and v4, so I have omitted this one. Should I post this afterwards? Greetings Stefan On 11/24/22 08:34, Stefan IT wrote: Hello all, I have a strange problem with my BackupPC 4.4.0 installation. With two hosts to be backed up, the "File Size/Count Reuse Summary" shows a too large value for "Totals -> Size/MiB". The system to be backed up is about 77 GiB ("du -sh /" shows 77G). Nevertheless, BackupPC shows 106110 MiB. Where can this difference in size come from? In an old installation, with BackupPC 3.3.2, the size is displayed correctly. How can I investigate this error? What information is needed to investigate further? Thanks to all! Stefan, Can you post the exact contents of the backup summary from a specific backup xferlog. For example I've posted the summary of backup # 59 from my xferlog following here: > Xfer PIDs are now full backup 59 complete, 100171 files, 7590653598 bytes, 0 xferErrs (0 bad files, 0 bad shares, 0 other) BackupExpire: cntFull = 4, cntIncr = 2, firstFull = 0, firstIncr = 2, oldestIncr = 54.8124652777778, oldestFull = 85.274849537037 Removing unfilled backup 56 Xfer PIDs are now 492118 < That way we get a fuller picture in a format that is familiar to us all.
