What's your version ?
If you can stage during backup, you must be able to recover during backup.
(did you try to recover a file or from a recover -S ssid ?)
Any error msg in the daemon.log ?
I just tested it on a fresh 7.2 unpatched build. Created AdvFile Dev, labelled
it.
Backuped a directory #1.
Backuping a directory #2 and recovering directory #1 like a charm, no error, no
pending.
Backuped a directory #3 and staged directory#2 to another pool, no prob.

Objet : Re: [Networker] Restoring from Disk Backups
I thought this was the case as well, but in writing a response I decided to
give it a try. I am also unable to Backup and Recover at the same time from
an advanced file type device. As long as the backup is running the NW
client says :busy retrying in 30 seconds. The Backup is going to the
readwrite volume and the restore was pointed to the _AF_readonly volume. Is
there some part of the backup that is touching the _AF_readonly volume? Or
do I just have something misconfigured?
