Backup Qnap Data Volume to Truenas offsite

[Enquiries]

I have a TS-464 at home wich has a Data Volume to which I Copied all of my backup drives from my closet using SMB and more importantly YEARS of Photos usin HBS 3 to backup all my cloud content from skydrive, icloud, google, samsung, att, Dropbox Etc Etc

I have a server (just a PC) at my office away from home on which I can run a virtual Truenas installation with four raid drives.

What is the easiest way of automatically backing up my Qnap Volume monthly offsite. I am a new user of truenas. Thank you. Love your content.

There are quite a few options.
You can use Qnap cloud https://www.qnap.com/solution/myqnapclou...age/en-uk/
You can alternatively use Backblaze.

Or you can get a new NAS to locate remotely at relatives or friends and backup to there.
