Hi,
I want to schedule a backup to a external HDD which is connected with USB. When I go to backup and restore app > external backup, it does not showing my HDD.
Anyone can describe this and how can I backup nas to a external HDD?

Re: Facing problem backup to external HDD
Does it show the external USB HDD in the External Devices > Hard Drives? How about in the Storage Manager > Drive?

Yes. It's showing in External Devices > Hard Drives. But not showing in External backup.Nazar78 wrote:Does it show the external USB HDD in the External Devices > Hard Drives? How about in the Storage Manager > Drive?
As I connect the HDD with USB so I think it won't show in Storage Manager > Drive

Re: Facing problem backup to external HDD
IIRC there was a report previously on older firmware that external drives showing in the Storage Manager. No updates from the user so not sure what's the conclusion.riaj uddin wrote:As I connect the HDD with USB so I think it won't show in Storage Manager > Drive
Just checked, no issue here with the latest firmware updated today.riaj uddin wrote:Yes. It's showing in External Devices > Hard Drives. But not showing in External backup.
1x flash drive, 1x SSD (used as cache hence not shown), 4x HDD. If you don't see this, you should open a ticket with Asustor Support.
