How do you back up your FreeNAS?

Wow... I don't, "nuked from orbit"... I might not need to worry about recovering my data after that.

It's the only way to be sure.

Hi Guys,

How do you back up your FreeNAS data? Sync to cloud or backup to external media?

Regards,
Sean

I replicate a remote freenas to my local freenas. Replication is the best way to go as it doesn't take it long to figure out the differential from one system to the next and overall works better than rsynch..IME

If I was to backup onsite, what would be the best practice?
-1 big external Hard Drive plugged only when backup is needed (connected esata)
-Add another pool in FreeNas RaidZ1 used for backup that is always on?

I haven't decided on the main pool configuration yet, but I am looking at a pool size of 12TB.

In our small business, I've bought a single 14 TB SATA disk that I keep at home in case our office burns or floods. I bring it in weekly and a use a few 'zfs send' commands to sync the newest data to it, then I eject the disk. Worse case we lose a week of data, which isn't too bad for us.

Two pools using ZFS snapshot and replication (until that caused kernel panic and I now interim rely rely on rsync).
These were previous on different machines but are now within same server.

Some 25% is critical data and backed up to Backblaze using the builtin functionality.
Selected ZVOLs used for ESXi iSCSI are written/dd'ed monthly and sent to Backblaze as well

Backing up your main Dataset to another Dataset in the same FreeNas Server cause Kernel problem?
It is not recommended?
