I'm trying out the backup feature in Qubes but getting an error.
I'm trying to save VMs totaling 22.4GB in size on a USB stick with 63GB
free.
At 19% progress is get:
"[Dom0] Backup error!
ERROR: Failed to write the backup, VM output: cat: write error: File
too large."
Is there a maximum file size for backups? A RAM limitation (I have 8GB
RAM and when I do the backup about 6GB is free)? Something else I'm
not thinking of?
I am able to do a small backup, such as just Dom0 itself.
Also a general question about backups: if I do a backup and then
restore, will it add what I backed up to what is already on the
system? Or completely overwrite everything? For example, if I have 10
VMs and backup 3, then restore the 3, will it just overwrite those
three and leave the other 7 alone? Or will I only have those 3 and the
other 7 are wiped out?
Also, be sure you didn't make the mistake I made once. I (stupidly)
mounted by backup USB stick in Dom0. Then, when backing up Dom0, it
tried to back up all the data on the backup stick, which of course kept
increasing in size as more stuff got backed up onto it. I've since
learned to use a USBVM, and mount the stick in a dedicated BackupVM.
