USB backup on OS 6.2.4 Ultra6 fails
I am having difficulty with backing up my Ultra6 via USB to an external Seagate 4TB USB disk drive, namely:
Logs show the device is connected to:
usb_devices
usb_storage
While the backup jobs configure themselves (in /etc/frontview/backup_jobs.conf) as (using USB Back Top, USB Front and USB Back Bottom):
Has anyone encountered this issue and solved it? I have the 4TB plugged into the Back Left port and a UPS plugged into the Back RIght port. Nothing plugged into the front port. I have not swapped or tested other ports yet but will do so this weekend.
Any help would be greatly appreciated.
- USB backup to a specific USB port fails with "Backup: Error backup job '<sharename>': destination cannot be accessed."
- USB ports listed from the dropdown in backup configuration include "USB Back Top" and "USB Back Bottom" while the Ultra6 has USB Back Left and USB Back Right ports on the back
- The USB device have iterrated from USB_HDD_1 through to USB_HDD_3 (negating the solution to backup to the USB share)
Logs show the device is connected to:

The port mapping for the Ultra 6 has been added to a future firmware release, but I cannot provide an ETA at this time.

- mdgm-ntgrNETGEAR Employee RetiredYou would need to configure the backup job to backup to e.g. USB_HDD_3 if that is the disk you wish to backup to.
We have not mapped the ports to e.g. USB Back Top. - JophusLuminaryThis solution only works while the disk remains in the NAS. When it is disconnected and reconnected it iterates to USB_HDD_4 etc and the backup jobs fail.
Any other thoughts? - mdgm-ntgrNETGEAR Employee RetiredThe ports are mapped correctly for OS6 NAS units e.g. the 316.
- JophusLuminaryThanks.
Does that mean the Ultra 6 and OS 6.2.4 has incorrectly mapped USB ports between frontview backup screen and the physical ports on the device? - mdgm-ntgrNETGEAR Employee RetiredWell we haven't added the port mappings for the USB ports and considering the unsupported status of running OS6 on the Ultra 6, I can't see that changing.
- JophusLuminaryThanks for your prompt responses. Very much appreciated.
To close this issue out, are you aware and could you provide me with a general direction to look towards, within the Frontview configuration files, as to where this mapping exists? - JophusLuminaryFound similar thread..
Thanks for helping.
http://www.readynas.com/forum/viewtopic.php?f=25&t=77555&start=45#p433310 - JophusLuminaryOn restart I now have a USB_HDD_4 partition. It appears USB on my legacy Ultra 6 running OS 6.2.4 just won't elegantly handle USB backup.
I'll try the front port this evening but I am not holding any hope of it working. Will update in due course.- JophusLuminary
To confirm, all legacy Ultra 6 USB 2.0 ports cannot be accessed in 6.2.4 via the "Back up to Front/Back Top/Back Bottom" ports. Given the nature of the changing USB share name target, backing up to USB is not robust on this model.
Netgear, it would be greatly appreciated if the USB mapping on legacy products (e.g Ultra 6) were to be correctly implemented/mapped in the new 6.2.x and 6.3.x OS.
My solution was to buy a Readynas 102 2-bay, ARM-based NAS, install the external drive into it and backup over gigabit network using RSYNC.
Why?
- Ultra 6 has USB 2.0 ports (~28MB/s) while an RN102 connects via gigabit (41MB/s by my experience) AND has USB 3.0 ports
- I appreciate the fact Netgear UNOFFICIALLY "SUPPORTS" (by this community and forum) the installation of 6.x onto legacy devices
- BTFRS, snapshots and the improved OS6 interface are worth the price of losing direct USB 2.0 backup functionality
- 2 bay NAS allows for onsite backup expansion as I expand the primary Ultra 6 NAS
At the end of the day the incorrect mapping led me to double down on 2nd Netgear ReadyNAS. It would be greatly appreciated if Netgear could return the favour and map the ports on the Ultra 6 correctly.
Here's hoping!
