I'm just configuring a new BackupPC v4.4 (on Debian, using packages from the repo), and encounter this kind of errors systematically. It's not a corruption due to some hardware fault, but clearly a bug in BackupPC. All my backups seem to work fine (no xfer error), but the nightly cleanup show lots of errors like 2024-09-16 12:00:05 admin1 : BackupPC_refCountUpdate: missing pool file 81db068be9b224623dabacf4c68f109d count 2 2024-09-16 12:00:21 admin : BackupPC_refCountUpdate: missing pool file 08c8a1eb695a242d2bd7eaea1f3edab6 count 2 2024-09-16 12:00:32 admin1 : BackupPC_refCountUpdate: missing pool file 9223a6f7e93e469f2ac7545cd2cd6400 count 2 2024-09-16 12:00:40 admin : BackupPC_refCountUpdate: missing pool file 1c9e19403c2e95778baf7b1010c3982b count 2 2024-09-16 12:00:45 admin : BackupPC_refCountUpdate: missing pool file 25f002208fe299e9b0cc92d17c748ca3 count 2 2024-09-16 12:00:47 admin1 : BackupPC_refCountUpdate: missing pool file a92d3b961a8f02c92daae28df16a245f count 2 This is running on a full NVMe ZFS pool (RAID10 like with 4 mirror pairs), I tried with BackupPC's compression off (and using ZFS compresseion), or with BackupPC's compression (disabling ZFS compression) with the same outcome. This pool is used for other stuff (1 relatively busy mariadb server in a VM, one Proxmox Backup Server storage pool), and everything is working correctly. Only BackupPC is having issues. Looks like I'm not the only one affected, see https://github.com/backuppc/backuppc/issues/494 (although in my case, using BackupPC's compression is not fixing the issue). I tried 3 times to wipe and start from empty pool, but this comes back everytime. So there's a bug in BackupPC. It might only be triggered on ZFS (or maybe it's related to the speed on the underlying storage, as this one is really the fastest I ever used). But there's something. For the first time in more than 18 years of using BackupPC, I think I cannot trust my backups anymore. The fact that there's no way to fix these errors is very worrying. -- Daniel Berteaud _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
