vzdump temp dir delete stale data?

Hi all!
my proxmox environment is consuming near to 100% disk space.
I figured out my CTs only consume around 50% of storage. I found a folder called "/vz/vzdump_tmp_dir" which is configured in /etc/vzdump.conf as tmpdir.

Currently, no backups are running.
In the past, a couple of backups failed. (this is another thread ... one day!)

To my question: Can I delete all data in tmpdir: /vz/vzdump_tmp_dir/ without issues?
Any suggestions? Delete + Reboot? Reboot + Delete? Are there any "tidy up tools in board"?

Thanks in advance!
In case no backup is runnning it should be fine to just delete the files of the failed backups. Maybe also a fstrim -a afterwards in case your root storage uses thin-provisioning to free up the space immediately.

Thanks mate!
I deleted the files and nothing major happened yet.
I will keep an eye on this.
