Hi all, I'm trying to solve a problem revolving around my backup strategy. I have a number of services running on a homeserver. Backupwise, the most impactful is Nextcloud. I converged on Nextcloud for all data, to be able to easily add to it (clients on different platforms, auto upload) and...

Hi all, I created an NFS file server with the container on SSD and the data on HDD. This way the container is somewhat snappy, with the HDD providing bulk. Using bind mounts, I face difficulties backing up the complete container including data to PBS. How should I compose the container, so...

Hi all, Over an hour and a half ago I started a restore task of a 400 GB container backup. Up to now, restores have been of VMs and containers in the lower tens of GB range, which would ramble for a while and then complete. This one just 'sits there': recovering backed-up configuration...

Hi all, Sorry for crossposting My main container (mail, messaging, calendar, phone backup) is offline (and has been for some 10 hours) due to resizing the LV from 3,6 TB to 0,4 TB. This is an LV on a thin pool; it has previously been filled to about 3 TB before I moved most data to other...

Hi all, I have a container on a thinly provisioned LVM volume. I want to extract the disk that backs the thin volume out of the system running Proxmox, but run into the issue that thin volumes don't support shrinking. After moving stuff out of the way, there is a lot of air in the container...

Hi all, I'd like to ask for input on something I'm considering while migrating and consolidating some machines. Current situation: * Multiple machines (some containers on PVE, some bare metal) have multiple years of data * New data, in aggregate over these installations, is added at about...

Hi all, I have a container backed on a mediaset of five LTO3 tapes (tape0-tape4). The fifth tape now returns an error. I am aware that LTO3 is not officially supported, but in practice things use to turn out quite well. This is the log of the task: 2025-05-31T22:34:14+02:00: update media...

Hi all, I have an external PBX for remote backup. At the moment the web interface is accessible via the Internet. I have SSH access via public key for root and disabled password access. Of course root now can not log in via the web interface, which is the way I like it as long it is on the...

Hi all, (Excuse me, this was supposed to go into the PBS subforum) Is there a way to estimate / extrapolate runtime of backup actions, or guess whether it finished or is still running? My PBS runs on low end hardware (4TB@7.2k spinning SAS, non-RAID, with LVM cache on SSD, quadcore Atom D525...

Hi all, I locked myself out of a container. The container runs Debian with Yunohost; it was installed with a sudo account and root login disabled. One way or another both my accounts with sudo have no sudo anymore after an unexpected power cut. User accounts are managed via LDAP on the...

Hi all, Edit: the 'not deploying' bit turns out to be a known problem , to be fixed upstream I am in the process of supplying hosts on the LAN with Letsencrypt certificates. I found the ACME plugins in datacenter and node, and an option to manually upload a certificate via the Web GUI or...

Hi all, I started a backup to tape. There were about one and a half tape free (in a four-tape set), I did not think of allocating more tapes to the pool. Unfortunately, there is more data to back up than there is tape in the pool. The task ended in `alloc writable media in pool 'tapeset'...

Hi all, I just completed backup and verification of a snapshot and started a task to write it to tape. There are six snapshots of this container, the fifth of which failed verification. Only the first snapshot has been written to tape previously My intention was to write only the last...

Hi all, I'm contemplating replacing a mail server with PMG. The installation options that are relevant to me are 'on top of Debian' (together with PVE) or 'Download the LXC template' The mail server sees a fairly low volume of mail. Is there any benefit to one or the other option? The only...

Hi all, TL;DR: I created a thin volume and a mount point, but forgot to mount it before creating a datastore. The result was not what I expected. Not finding LVM thin explicitly in the PBS docs, I asked whether a datastore on thinly provisioned LVM would work. Conclusion: yes it does, just...

TL;WR: This must have been a one-off run-together of circumstances 4 snapshots of a backup failed re-verification 8 corrupt chunks in snapshot 1 running 5th snapshot backup while verifying 1-4 5th snapshot also fails verification 3 different chunks restore snapshot 1 from tape (2...

Hi all, TL;WR: I had a snapshot that failed verification Restore from tape did not correct any chunks On re-verification it turned out that the verification had incorrectly flagged a number of chunks as failed Lessons learned: use server grade hardware or exercise patience (ie, don't run...

Hi all, I'm on PBS 2.4.x. There is an external tape drive connected to the system, but it is not running 24/7 as I need change the tapes manually anyway. The result is that tape backups occur less frequently than planned in the job. So there is a bit of a backlog of un-taped backup snapshots...

Hi all, I just started with Proxmox and the forum. My hardware is a lot simpler than most things I read about on the forum, still it manages to puzzle me. On initial installation I got a single SSD, on which I put ZFS in RAID0, ie., a single disk pool. I set copies=2, and had a root partition...
