With 11.2-U6 in place, I'm now exploring online backup to Backblaze. At the moment it is only using a third of my upload bandwidth, and I'm curious whether this can be increased.
I have a low power FreeNAS server with 16gb and 3 4TB drives in RaidZ1 (call this Main). I am replicating all of the non-media datasets to another lower power FreeNAS server with 8GB and one 4 TB drive (adequate for now) (call this Backup, which is all it does). The media datasets I'm replicating to a local USB drive, as I am less concerned with that. That all seems to be working fine.
So Backblaze would be my third, physically separate, backup. My upload speed is 30mb/s; my speedtests are regularly in that range. I have Backblaze configured as a Cloud Sync sync task on Main to backup one dataset on Main, encrypted. It just completed uploading 128GB now at around 9mb/s, taking just on to two days. Throughout the CPU usage was very low, there were gobs of memory, and internally data moves from Main to Backup around 500mb/s, so I'm not seeing an obvious bottleneck.
Before I configure other datasets for upload, or figure out how often the Cloud Sync should run, is there this speed normal? Is there something I can do to improve the speed?
