I have backups running to a Samba storage with 2 TB of space left and they were working fine until recently i get an out of space warning. Has anyone come accross this before

You are 100% sure that the samba share is working and correctly mounted? The most common reason for this problem is that the share has become not-mounted and backups are being written to the mount directory on the rootfs.

Is there an easy way to check that? When i log on to the samba from windows i can see the backup files so been assuming it's mounted correctly

Ok, but are those the _current_ backups? Or some old ones?

I dunno, maybe log into PVE and type "df -h" to see what's mounted and how much is used. This is basic Linux admin stuff, nothing really to do with PVE at all. There are many, many guides and videos you could look up.
