Backup to NFS - Data Store full of junk nfs files

epsoft Lv1Posted 18 Jan 2023 01:29

I have several HCI installations on various environments.
In almost all of them I noted that sometimes happens that the NFS DataStore used for backup target will be filled up wit junk files named .nfsXXXXXXXXXX when the backup process does not complete successfully.
When I launch the Junk Scan on archive it does not find anything, but if you browse datastore you can find a lot of that files, they'll grow up unlimited and can fill up datastore up to 100%
Maybe these files are partial data storage of the backup process that, if not concluded successfully, will remain pending and occupy waste space on storage.
I suggest that the Junk File scan will search and find these files also, to cleanup and regain spaces

Aware of that, but in the example in attachment there's a 1.8Tb temporary file more than a year old.
Moreover, the datastore is used only for backup and in certain cases you can find that more than 50% of the spaces is wasted in these files
