Issues backing up readynas 214 to external USB device
Model: ReadyNAS 214
Current Firmware: 6.7.2
I have a readynas 214 that I previously had backing up the full nas volume to an external usb3 docking bay to 4 TB Seagate hard drives using the built in netgear backup manager. The system was updated from 6.7.3 firmware to 6.7.4 and the backup failed after the firmware update. The nas would crash after the start of the backup job with an error message on the LCD of "mb_shrink_cache_scan+15C" The only way to recover was to pull the power and reboot. After reboot the backup job showed it had been cancelled with no log generated in the backup job and no logs generated in the system log.
I have tried manually downgrading the firmware to 6.7.2 (because 6.7.3 was not available for download and netgear tech support would not provide a download for the original firmware) and the issue still occurs but with occasional new errors which include "mb_cache_entry_get+68" and "kmem_cache_alloc+60"
I factory reset the nas and reconfigured and reloaded the data and tried backing up again and it still fails. I have also tried granularly removing folders from the nas and attempting to backup to see if an individual file or folder was causing the issue since some files do get copied to the external drive before the backup fails (The file and folder it fails on appears to be random).
Tech support directed me to run a memory test on boot. I left the job running for several hours and it never appears to complete. At that point netgear tech support insists on paying for tech support to fix a problem that appears to be caused by their firmware update.
Wondering if anyone else has encountered a similar issue and has a fix or has any insight into a possible fix.
Thanks
I have managed to get the backups to complete. I did a hardware factory reset from the boot menu, updated to most recent firmware, reconfigured my backup jobs to backup individual shares rather than the full volume and reformated my backup media to NTFS rather than EXT4 and the backups have now completed successfully twice in a row.
Fingers crossed the issue is resolved. Thanks for the help.

Did you try on 6.7.5?
Did you get it working on any F/W? If not, what makes you think the issue is the F/W?
I did try it on firmware 6.7.5 before downgrading. Sorry, I forgot to mention that. I've haven't tried any other firmwares other than 6.7.2, 6.7.4, and 6.7.5 since the backup worked for several months on firmware 6.7.3 (which was the out of the box firmware).
I'm not 100% sure it is the firmware causing the issue but the backup ran without incident for several months and failed immediately after updating the firmware. It could be something else I suppose but what I'm not sure. It doesn't appear to be a corruption in the the data being backed up as I have factory reset a couple of times now and tried backing up with different sets of data with the same result. Which to me leaves hardware failure as the only other thing I can think of but netgear support insists it could not be that if it is only the backup manager failing.
- Can you try with another USB device connected to another USB port with another USB cable? If you can, try with another filesystem on the USB device as well.
