[BackupPC-users] Copied config with old hostname and backing up myself by mistake
Hi all, We're using BackupPC in two datacenters backing up local VMs and bare metal servers and things in the opposite DC. I've spotted a weird thing where one DC server is supposed to be backing up a host in the other DC, but it actually turns out to be backing up itself because we messed up copying the BackupPC config. For example: * BackupPC node 1 is gavin.suretec.net in DC1 * BackupPC node 2 is henry.suretec.net in DC2 Now gavin.suretec.net BackupPC server config was copied to the new server in the other DC onto henry.suretec.net henry.suretec.net server config in BackupPC says the host is gavin.suretec.net and the server URL is gavin.suretec.net when it should be henry.suretec.net really. DNS is correct in that gavin.suretec.net is in DC1, but even after changing all the BackupPC server details to henry.suretec.net, it's still treating henry.suretec.net as the other host (gavin.suretec.net), i.e. it's not connecting to gavin.suretec.net to rsync data back. It's just rsyncing to itself. I just can't figure out why it still thinks it's the other BackupPC node. There are some local database dumps done to that server I want to pull down to the other BackupPC node via normal backup jobs run via BackupPC. I'm not trying to backup BackupPC data, just a folder. I originally checked the folder that was rsyncing in case rsync saw an underlying mounted filesystem or something, but it's not that. I've restarted backuppc too. Make sense? What else can I check? I've ssh'd to the other node as the correct user and it connects as I'd expect. -- Kind Regards, Gavin Henry. ___ 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/

Hi all, Any pointers would be greatly appreciated. Does the project or anyone subscribers offer paid support? We're also looking for help to migrate to v4.

Hi Les,
Yep, checked the alias. That's empty. /etc/hosts I checked first.
nmblookup -A returns correct IP address.
Sooo strange.

Re: [BackupPC-users] Copied config with old hostname and backing up myself by mistake
Hi all, Just a follow up after I engaged my brain. So because this config was copied from a backuppc server in another data centre and that server has now become "remote", i.e. not the local box, the RsyncClientCmd didn't have any SSH in it So it was: RsyncClientCmd: /usr/bin/sudo $rsyncPath $argList+ RsyncClientRestoreCmd: /usr/bin/sudo $rsyncPath $argList+ when it should have been: RsyncClientCmd: $sshPath -q -x -p X -l root $host nice -n 19 /usr/bin/ionice -c 2 $rsyncPath $argList+ RsyncClientRestoreCmd: $sshPath -q -x -p X -l root $host nice -n 19 /usr/bin/ionice -c 2 $rsyncPath $argList+ In case others do what I did :-) Thanks. ___ 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/
[BackupPC-users] Rsync and swapping the hard drive mounted at /var/lib/BackupPC - backups vanish
Hi all, On my home desktop my backups are going to a 2TB usb drive. All good. It's filling up, so I bought a 4TB usb one and have rsynced all data on the same type of filesystem too (rsync -av --delete) but when I mount it and restart BackupPC, nothing shows. Put the old drive back and re-mount/restart and they are all there. What have I missed here? Thanks, Gavin. ___ 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/

Sorted. Permissions as always. Thanks for your second pair of eyes Kenneth! I'm re-running the rsync like so for selinux too (due to the dot at the end of the directory perms): rsync -av -X --delete --dry-run backuppc/ /var/lib/BackupPC/ ls -lhd /var/lib/BackupPC drwxr-x---. 7 backuppc root 4.0K Jan 25 22:23 /var/lib/BackupPC ___ 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/

Each sites big BackupPC box does both sites with rsync very well. I know LINX use this two that's why we did.
