Problem: Readynas 312 back-up to external HDD (Mac)
I'm sorry there is no short version for what I need to ask you, so here we go: I am a Mac-user. I have a ReadyNas 312 with 2*2 TB in Raid 1. About 450 GB in use. Firmware installed is 6.1.8 - and t...
You shouldn't need to do a factory reset to upgrade to 6.2.2. Some users are having issues with 6.2.2 (I am not myself, but several posters are). So I wouldn't rush to install it. It wouldn't surprise me if there were a 6.2.3 in January...
But you should be able to back up the NAS anyway (as RAID doesn't guarantee your data is safe).
Your problem is that snapshots are being saved to the external drive. They take little space on the btrfs disk volume, but when copied to the external drive every snapshot has the same size as the main folder did when the snapshot was taken. This is not related to the format of the external drive.
One work around is to adjust the settings so that snapshots aren't accessible [they are still there, but only seen by administrators], and back up share by share.
There is a somewhat more complicated work around - which is to use rsync for backup, and exclude the snapshot directories.
You could also delete all your snapshots manually and temporarily disable them. That will work once, but it is better if you have a regular backup schedule for the NAS.
