I have Urbackup 2.1.19 running on an Ubuntu 16.04 LTS Server with a 150 GB Root Partition and 2 TB Data Partition. Whenever Urbackup Server is running any jobs, it saves the backups to the data partition, but it also slowly uses up space on the root partition, and whenever the root partition fills up Urbackup Server crashes and the space frees up the root partition again back to 130 GB free on the root partition. Any help on this issue or any steps to take to help diagnose this would be greatly appreciated. Thanks!
look at at /usr/local/var/urbackup in addition to the path you set in urbackup.
also look at /tmp during a backup for fils owned by urbackup
also try unchecking Temporary files as file backup buffer in advanced
you can use ncdu to quickly fins where the disk space goes
you can use mount with bind option to mount a partition in two places
I have the exact same problem. Did you figure this out. No matter what / gets filled. Using ncdu doesn’t show where the hidden files go. If you restart urbackup, the space erases.
Hi
By default ncdu shows hidden files.
Actually you need to run something like ‘ncdu /var/data/’ or whatever is your mount point.
If it wont shows via ncdu, then another low possibility is “lsof | grep -i deleted”, but i really doubt that’s the problem.
I dont think there are other a lot possibilities. Space could be consumed by something like inode and that s a super low probability that inode use more space than data itself.
Maybe zfs/brfs snapshots or something can use data in unexpected ways, but that would be too file-system specific for me to diagnose like this.
its the URbackup program. If I reset it, I get the space back. I am restarting the service.

The backup is running and filling up / above.
Output of ncdu doesn’t add up either
