  1. Retention & sync jobs

    Hello all, I'm thinking about migrating to PBS for on-site & off-site backup. While the connection between headquarters and branch office is relatively (very) slow, the backups have always lagged behind for some days (using copy job in Veeam). The lagging is not a problem while is ok that i...
  2. Optimization possible?

    Hello! I've been using PBS since about a year now, love it! I know it is recommended to run the server with SSD data disks. Unfortunately I cannot afford it and have to use spinning disks.

  3. How to handle datastore on NFS share that is offline most of the time?

    Hi, Right now I got a single PBS-VM1 on Host2 that got its datastore from Host2 via NFS. And this PBS-VM1 and NFS share is available all the time. Problem is that I can't backup Host2 or guests on it, because if Host2 fails there would be no running PBS to restore them from. I also got Host1...

  5. [INVALID] Garbage Collection fails for non-existent VM

    EDIT June 15, 2022 - I was looking at old logs. This is NOT an issue. Board admins, please delete this entire thread as it is completely invalid. I manually deleted chunks. Because I did that, I was unable to perform syncs. To fix that, I deleted my Datastore and recreated it. (See...
  6. Exclude groups in sync

    Hello everyone. Is there a way to exclude certain groups (VMs/CTs) from a sync job? I'm syncing to an usb HD. And while my PBS instance keeps a lot of backups I only want some of them in the usb storage. Can this be expressed using Group Filter? Best Regards/Viele Grüße ....Volker

  11. Limit number of backups sent to remote (off-site) backup server

    Hi Everyone, Perhaps I've missed something in the forum or in the manual, but is there a way to reduce or limit the number of backups sent to a remote PBS? For example, say my on-site backup server had 8TiB and was used for A LOT of backups, but my off-site was say 4TiB usable, could the sync...
  12. PBR Remote Sync - Limiting the sync

    Our main backup server has 20+TBs of available storage (our colo server), while our offsite only has 12TB (public bare metal cloud). Since I can't easily get additional storage at my offsite location and I only need to offsite store a smaller set of last-resort backups (say, the 5 most recent...

  16. How to back up a folder only

    Hello there! I'm currently in the process of planning out a system for a new setup I'm working on. This will, of course, include PVE to be the host of some Windows VMs and other smaller stuff. Also, I want to host some sort of NAS (samba-only is enough) from that same host/server machine. So...
