Amazon Affiliate Store ️ we used on Kit (affiliate Links) ️ ITProTV. Even if we overlook the convoluted way to get it working with freenas, it still needs 1gb of ram per terabyte to back up. Compound this with the heavy ram requirements of freenas (because of ZFS), and you need a ton of ram. As an example, minimum requirements for freenas is 8gb of ram. Backing up 10tb? I plan on using FreeNAS, which has B2 compatibility, but I'm guessing I'd have to either create a jail or VM to back up all the data using a personal account, possibly through a Windows 10 installation and iSCSI? Are there other services that are as easy to use and dependable as Backblaze that don't mind home servers using unlimited backup?

Are there other services that are as easy to use and dependable as Backblaze that don't mind home servers using unlimited backup? With WIndows, I back up 110TB for $10 a month on regular BackBlaze. I dont believe you can use the VM trick to get around this, where you have Windows host OS and FreeNAS VM with shared drives. BackBlaze wont allow you to backup network share drives from another 'computer' from what I remember.


  • I have a FreeNAS setup
  • I want a cheap offsite backup solution
  • Backblaze only offer S3 storage solution
  • I have virtual machines on zvol to backup (not just files)
  • ZFS send/receive is very convenient if you have another zfs system in other

I choose zfsbackup-go, this tool use zfs send/receive to generate archives on S3 storage space. This software is not ready for very critical use, still in « beta » missing some features like deletation on remote location from the command line.

  • Can backup zvol as well as dataset
  • Differential backups based on snapshots
  • Encrypted backups
  • Compressed backups
  • Compatible with all S3 solutions


  • You can’t use backups without re-import in a ZFS pool (so real backups
    not a archives solution)
  • Still in beta

How to

  1. (Optional) Build zfsbackup-go for freebsd with crosscompile from a linux
    1. You need GO
    2. git clone [email protected]:someone1/zfsbackup-go.git
    3. GOOS=freebsd GOARCH=amd64 go build -o zfsbackup main.go
  2. Generate a gpg key gpg --full-generate-key
  3. Export the private/public gpg keys

    1. gpg --list-keys
    2. gpg --export-secret-keys -a keyid
    3. gpg --export -a keyid
  4. Create the S3 credentials you need
    I use BackBlaze because it’s the cheapper one, but you can use every S3 storage service or implementation you want.

  5. Configure periodic snapshot in FreeNas

  6. Configure zfsbackup cron task

    • You need to ensure the schedule is after the snapshot
    • I have develop a very little script to have a more simpler crontask because zfsbackup only support one Dataset at a time
    • Command DATASETS='Tank/Dataset1 Tank/Group/Data1' /root/


  • This solution offer very good performance like 15MB/s during backup operation with only 10% cpu usage on Xeon D1521. My Orange ISP uplink is the limitation here.
  • With incremental snapshot, BackBlaze is a very effective solution at low cost like less than 60€ a year for a 100GB on disk backuped VM.

Today, we are going to talk about the topic of cloud storage backups. There are several things that we have to look into when selecting a NAS, and backup/replication is always one of the most important. Having RAID protects against data loss in the event of a drive failure, but there are other data loss risks that need to be taken into account. Regularly backing up your data always keeps your data safe in case of fire, theft, or any possible hazard that might damage your data storage device. Thus, backup features are always the first thing we need to dig deep into. In case you are not aware, the officialHybrid Backup Sync just released on QNAP NAS and is available in the App Center.
