Hi, I want to backup a TrueNAS VM after the initial setup to another TrueNAS machine in case the original server goes capult for some reason.
First thing I tried was replication, but while the VM has 304 GiB the replicated image was nearly empty. So then when I did a "du -h" on that mount point I found that the actual storage used by the VM is not accounted for in the file system. That is a 444 GiB pool and only 140 GiB is accounted for -- i.e. the 304 GiB used by the VM do not seem to be part of the visible file system.
Any thoughts on what is going on, and more importantly, how can I make a copy of the VM for posterity?
Thanks!!
