Backblaze will backup up your external drives, however it will not back up NAS. To get around that I use ChronoSync to copy the data from my NAS to a external HD then backup the external HD up to Backblaze
And this kills BB for me right there. I don't HAVE an external drive that large (40TB), I'm certainly not going to go out and buy one ($1,500) just to satisfy an offsite backup service that I am paying for specifically to backup my image store, which is the NAS.
Of course, getting a RESTORE of a 40TB backup from BB (should I ever need to actually use the reason for the service) sounds like it would be a nightmare as well (they wouldn't send it all at once, with their limits). So that was already killing the idea of BB (
everyone should consider the scenario of RECOVERING your images should catastrophic disaster ever occur).
My solution was to buy an older used NAS (not worth much with it's older/slower processor and too old to be ineligible to use the more recent versions of Synology DSM). Put some lower quality drives in there (since they would only be spinning when I did the actual occasional backup) and store it offsite.
Note: this offsite NAS is my 3rd copy. So, full disclosure, because this would probably be too much for a lot of folk, my storage solution is thus:
- Main NAS: on all the time, enterprise drives
- Local RAS in a box: on all the time, backs up the main NAS every night (I assume BB wouldn't back this up either)
- Offsite NAS (older used NAS, lesser drives, stored offsite)
All three are RAID configured, of course, which increases number-of-drive requirements..

PS EDIT: the older NAS used for #3 above is easy for those of you that have had a NAS for a while and are considering an upgrade. Just keep the older one for this purpose. It doesn't have to have the exact same config (drive types/sizes, RAID type) as the new one—capacity is the only concern.
