Backup to USB drive fails
I have tried to use a Powered Seagate USB drive (Mystorage 3.0) to backup the data folders on our Netgear Readynas 314. The external backup drive has been cleanly formatted with Seagate's Format util...

i tried both.
First i formatted it with native EXT24 format as recommended and it kept dissappearing as a volume. then i formatted using Seagte's own format tool as FAT32.
Same result.
PS: The external Seagate USB drive works fine on several Linux/Windows 10 PC's

FAT32 can't handle large file sizes - is it possible that you are hitting that limit?

No the data folder I am backing up is only 232Gb so far. I tried NTFS yesterday with the same result so it doesn't seem to make any difference, have tried the native format, FAT32 and NTFS

Just to be clear, the limit I meant was the max file size, not the volume size. FAT32 is limited to 4 GB files (and some implementations might be limited to 2 TB).
How big is this drive? Most of the larger Seagate USB drives are SMR ("archival") drives, which have very slow sustained write speeds and often don't play nicely with linux systems. On option is to connect it to a PC, share it, and back up over the network.

No network would be too slow..
I think I'll buy a new external USB 3.0 drive and try that.Any that you'd recommend for this job?
