I am having a bit of a problem with my backuppc install that just cropped up recently. Most of my network runs the latest version of FreeBSD 14.0-RELEASE, and it has been running on FreeBSD for years.

So my backuppc server is in a FreeBSD jail on dedicated jails server (i-5 7500, 32 GB RAM), with backing storage that is NFS mounted from from my TrueNAS host.
Noted. [2]
I am backing up a total of 8 jails, 3 hardware servers, my desktop, my laptop, all running FreeBSD 14.0. I am also backing up my wife's desktop, which is running linux. I'm using rsync. Everything has been backing up properly, then one day about 2 weeks ago, backups on my laptop quit working. I started receiving the error message backup failed (rsync error: error in rsync protocol data stream...) R bpc_read: read past EOF; readSize = 1024, posn = 356352, fileSize = 0, bufferSize = 8388608 R bpc_read: read past EOF; readSize = 17408, posn = 0, fileSize = 0, bufferSize = 8388608 ... [ skipped some lines ] ... R bpc_poolWrite_updateMatches: can't open candidate file ... Since it is only occurring on these two hosts, but none of the other 14, can someone explain what is going on here?
Are you running the server from UPS? Because to me that looks like filesystem damage. If I'm right it could be a lost write at a power failure or something, or maybe it could be that a storage medium is on the way out. I'd want to know ASAP. To start with, can you run fsck or something like that on the TrueNAS host? [1] I note that this has been working for years, but all the same I feel the need to say that in my experience NFS has been truly awful for this kind of thing. Performance, reliability, everything. [2] NAS hosts have a habit of getting compromised, however from all you've said I have to assume that you're on top of that. But it might be worth considering the possibility. I wouldn't touch them with a ten metre pole. Putting TrueNAS and NFS in the same system seem to me like asking for it but I guess I have to keep coming back to [1]. :/ Can't really fault you for putting BackupPC in a jail, but I'd be more concerned about things attacking BackupPC than I would that the backup server might attack the rest of the network. My personal take on it is to run separate hardware for the backup server. -- 73, Ged. _______________________________________________ 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/
