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?


Likely the filesystem (FAT?) on the destination cannot handle files over a certain size. You may want to reformat it with a native Linux fs like Ext4.
