I have tried to backup my WD MyClouid PR4100 NAS with USB backup. All folders backup succesfully apart from the critical “Backups” folder share that I have to a USB 2 drive.
I have tried multiple external USB Hard drives, but all fail on this folder but back the other folders up OK.
I have about 10TB that I need to backup for this folder and have at 20TB drive.
Given it keeps failing and doesn’’t tell me why, when it fails I can no longer see other data backup up data either once I run the backup and it fails looking at the quickest way to back this up.
I have a copy of all other data on another drive Ok that i can read as long as I don’t try to backuo the Backups share on it.
Total space of all folders / shares is 12.5TB - so I have plenty of space on the 20TB Drive.
I am limited by the 1Gbit LAN port on the WD NAS so will take awhile. (like multile days using a laptop / PC to manually copy files to the USB drive attached to this.
Is there a way to find out why the USB backup is failing? if not - what is quickest methord to urgently back this backups shafe up successfully?
PS: I don’t have another WD NAS to backup to.
I haven’t yet purchsed my new Synology NAS which wilm replace this (I am waiting for Black Friday offers)
I could wait until i have this and then use acrtive backupo but don’t want to risk this incase my device fails in the meantime!
Any help and advice will be kindly appreciated.
