[SOLVED] Is possible Reinstall PBS and Recover all BackUPs?

[AlfredoF]

I made a very bad mistake, execute rm ./* in the root path / of the PBS server (version 2.0) and OS disappeared. If reinstall PBS on the same server, Is possible to recover all the backups in the ZFS local datastore?

 

[fabian]

that depends how far the rm got before you stopped it, and whether the datastore and '/' share a disk/pool. you might want to look into ZFS recovery first after taking a full backup of all your disks.

OK, thanks. The OS can not boot, so I think I'll reinstall and will lost old backups, is not so critical. Anyway I think I will need a backup policy for the backup server.

Thanks a Best Regards
Alfredo

OK, I've the PBS server back, how can I rebuild backups from zfs?

 

[AlfredoF]

I've imported "zpool import -f backupds1" and it seemes that all backups are there, now how can add this datastore? How can I rebuild the backup configuration from there?

Try to add datastore, but get an error:

SOLVED:

add datastore.cfg

/etc/proxmox-backup/datastore.cfg

datastore: backupds1
path /mnt/datastore/backupds1

Just adding a comment; I found this thread afraid of exactly AlfredoF experience.

II really wish there were a way to backup my PBS to disk, or to treat the store as a NAS and back that up using a whole range of tools (Datto, Synology etc.) and store offsite.
Doing a PBS->PBS sync will only perpetuate data problems. We need a distinct "2nd copy" backup. Me, I'd like to use DATTO NAS or TRUENAS for that.
