Sometimes it may occur that copy sessions complain about the number of devices available.

[64:25] Cannot perform copy operation due to minimum number of devices not large enough.
Minimum number of devices is 1, required 2.
Here an example where the administrator thought all backups selected for copy had used only one device.
Please keep in mind:
Integration backups use dependant streams during backup which requires the same number of devices during
object copy (as where used during backup).
The assumption here is that some of this sessions used more than 1 device.
In cases like above, it is always a good idea to verify all the sessions filtered by copy session for number of devices used.
