NAS Backup: USB or 2nd NAS?

[Deleted member 28741]

Whats the best way to backup a NAS RAID 4 bay drive?

1. Sheduled Backup to an external usb hdd ?. or
2. Scheduled Backup to another NAS Raid?
NAS?

If the former will the files be readable as FAT32 and so easily accesible if the NAS 4 Bay raid box dies
?

If the latter should the second NAS be RAID 1 or 0
?

Thanks in advance

My NAS (2 bay) is setup for non-RAID. Two independent volumes. One volume is the main with shares on the LAN. The other has no shares. It is used to keep a time backup of key folders on the other drive's volume. Last 90 days or so of file versions.

Then key folders are backed up to a USB3 external drive once a day. It's formatted by the NAS to ext3 so it'll write much faster than FAT32 format. I have a windows freeware tool to mount/read that drive, or ones removed from the NAS, should I need to. That USB3 drive is out of sight (of thieves).

VIP folders are backed up to the SD card always plugged in to the NAS. VIP folders also copied to another cheap/slow 1 bay NAS that's out of sight.
off-site cloud backup.. not used. To slow (my ISP uplink) and untrusted services.

All automated so I don't get lazy and not backup.
