Proxmox backup server 2.2-5 is not enough to support large snapshots verify？

[dater]

1、I have a 19T backup, each verification takes more than a day and each verification fails。
2、When I click on the details in the task summary, the browser freezes,the details output nothing I using the Chrome kernel。
3、When I installed the backup server, I directly used ZFS and Rpool for the storage pool。

PBS needs good IOPS performance. Its recommended to only use SSDs, with that the verify job also would be way faster.
Is there info why it fails?

thank you very much,
I planed add ssd as zfs cache,
but haven't any log show why it fails.

SSD cache won't help much with verify jobs as for that all the data (so millions of chunk files) has to be read, decompressed and hashed again.

You can doubleclick a job. Then a window will popup showing you detailed logs about that job with more infos why it failed.

check the log on the commandline:

proxmox-backup-manager task log <upid>

or find it in /var/log/proxmox-backup/tasks

1、my system version is Microsoft Windows [version 10.0.17763.1697]
2、chrome version version 103.0.5060.134 （64 bit） | Firefox version 99.0.1 (64 bit) I had the same problem with both browsers
3、When I click on the details in the task summary, the browser freezes,the details output nothing,
and the browser output error code out of memory
4、so I use the command line ,The results are as follows ↓↓↓↓↓↓↓↓



5、At this point, I think the pbs will have a memory overflow error when verifying large files, which causes the page to be stuck. I also recommend adding a percentage to the verification so that the verification progress can be observed。

Is your PBS host maybe just running out of RAM?

i guess you have to put quotes around the UPID on the cli, eg

proxmox-backup-manager task log "UPID:bkk:001....."
