This ensures I have everything set up properly and also adds the client to known_hosts. ___ 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/
Re: [BackupPC-users] Deleting backups
After excluding /home/backuppc from the localhome backup, I did a successful incremental backup of /home on the 24th. However, I noticed that the file server was very slow on the morning of the 25th and a number of overnight backups were still running. I suspect BackupPC_refCountUpdate was the culprit, driving high disk seek rates. I ended up renaming /var/lib/backuppc/pc/localhome and started a new localhome backup series. I am running 4.3.0 (manual build for Serbian on ARM). I have held off upgrading until an official build but it appears I need to upgrade to 64bit Bullseye which is not trivial.

[BackupPC-users] Deleting backups
I have a home file server that also runs backuppc for a number of other servers. Backuppc backs up /home (host localhome) on the file server so I can recover from accidentally deleted files. Originally, /var/lib/backuppc was mapped to its own partition which periodically caused space issues. I recently moved the backuppc data folder to /home/backuppc and mapped it to /var/lib/backuppc but forgot to exclude the /home/backuppc folder from backups of /home. Backuppc completed backup 325 and part of 326 before I noticed the problem. I excluded /home/backuppc from further backups and did a manual incremental backup which created 327 (partial backup 326 disappeared). Although the cpool size did not increase, pc/localhome is over 2GB bigger. I tried running "BackupPC_Delete -h localhome -n 327 -s home backuppc" in the hope that would clean up the pointers but it merged #327/home/backuppc -> #325/home/backuppc. I repeated the process with backup 325 which merged #325/home/backuppc -> #324/home/backuppc. Right now, pc/localhome/324 takes up 644MB while pc/localhome/327 takes up 1015MB, compared to under 15MB before. Is there a way to get rid of the unnecessary pointers to /home/backuppc or do I just wait for them to age out?___ 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/
