I want to use an external disk as datastore on my PBS installation, when I run the backup tasks on pve I've got an error (OS error 22) the error is caused by the format of the vzdump file, it contains colon characters as field separator of the timestamp that are not allowed by the exfat partition, is it possible modify the format name of vzdump files?
 
Hi!
I don't think this is because of the format of the vzdump file, but more because of the timestamp folder on the pbs datastore. We store the backups in <datastore>/vm/<vm-id>/<timestamp>/<index> and the timestamp contains a ":", which is an invalid character in exfat (https://learn.microsoft.com/en-us/w...fication#table-35-invalid-filename-characters). Sadly there is nothing to do about this.
Edit: you can always open a bug on bugzilla, but I can't guarantee anything :)
