Backups are a good start but you must also periodically test and verify the restore process. Any suggestions on how to implement a practical test procedure to verify that the backup/restore will work when needed?
I achieve immutable and air-gapped backups that can be stored offsite by using tape. With the right backup technology and processes you can make this pretty secure and able to recover from any number of different scenarios.
I use 2 NAS servers for backup. The first one is on the AD where only admins and the backup software have RW. The second NAS is read only for ANY AD user, including admins and the only way it mirrors NAS No.1 is by doing a pull replication/rsync. Any deletion can only be done by logging on to the machine directly with a different user and password, with a local cron job or with something like winscp but only from specific machines and again with a different account that is not part of the AD. Not sure if its an ideal solution or I have missed something, but at the time of setting it up to my mind it was. 😁 Once again, good video and as always informative.👍
Long-term cloud archival is so cheap that is not a big issue having 2 or more full copy and snap shots in 2 or more Differents locations. Many insurance (especially in nowadays with CCPA or GDPR Hiden rules to backup private data) require you save your backup encrypted in at least 3 location separated by at leas 100miles. In 2023 I highly suggest for any bussines that handle valuable data to have at least one employee with the ISO 27001. certification.
I use Borge backup and an Storage Box from Hetzner. Borge has the permission to delete his own backups but the Hetzner Storage Box is based on ZFS and makes Daily Snapshots which only can be deleted via web Interface. And my backup user has no permission to read or whatever the backups. So I think this is a pretty good approach. What are you guys thinking?
@@marcogenovesi8570 a tape library from someone like HP coupled with A backup suite like Veeam is 100% automated…. And the amount of hours the drive can do is not dissimilar to the amount of hours a spinning hard drive can do before failure rates grow exponentially
@@NickF1227 if it's automated then it is just cold storage with extra steps, if it's not isolated correctly then you can delete the backups, just like with a normal cold storage appliance. I have some horror stories about tape libraries. The amount of hours and/or writes is so different you can't even compare it to hard drives, tapes aren't meant to be written all the time, again, plenty of horror stories about people that kept reusing the same tapes for backups well past their end of life and were hosed when tried to restore backups
I think Tom covered that in the external hard drive storage. You need good people processes, so the drives or tapes are swapped. And tested on a regular basis.
Immutable means the data only can be written once and never changed. It can be deleted, but never changed. Think of the old WORM systems, Write Once Read Many. Folks do mix up immutability and retention.
In the example provided, why not have the cloud backup performed by the replicated truenas server, and have it access the first server via SSH using a key pair, that way even if the first truenas server is compromised that they then would not have access to the cloud provider nor would they have an avenue to retrieve the credentials to the second server. You could even add a cron script to check for a canary file with a known MD5 hash to prevent replications.
I have a 5TB pool to backup, my home network is only gigabit ethernet so direct usb should be faster? I think it's a replication task source > destination but I'll let an expert confirm that
@Lawrense Systems, Tom, thanks for the video.. Very clarifying... btw.. your link to TrueNAS Document on "Hardened Backup Repository for Veeam" does not appear to be valid anymore...
Are you all using TrueNAS’ snapshot replication (zettarepl) successfully? I spent months trying to get it to work and just kept hitting bug after bug while trying to replicate ~40TB. I eventually gave up and switched to zrepl.

Great information thank you tom

This is very helpful Tom, thank you.
Be great to see borgbase or something setup on Scale.
Thank you Tom!
second! and TrueNAS is awesome!

Thanks for the idea, I didn't know about Hetzner storage boxes. Looks really nice!
Thank you good sir ..
If you want immutable backups...tapes have been around for decades? :P
Correct! There's even support for WORM tapes. Very odd he didn't mention any of this.
Tape backups aren't automated (unless you have the fancy bot stations) so now it's down to human error. They also wear out

That could work as well.
Compartmentalization is a good thing.
14:37 do you connect it directly to your TrueNas server or connect the usb drive to your pc and copy the data over ssh?

@@LAWRENCESYSTEMS Thank you!! Keep on rocking ! Your videos are invaluable!
Consultants who know what they are doing configure only full-automated backup solutions, no user involvement required.
Yup
root smb share is broken for anyone who set it up in version 11?
cron job to print the data on paper every now and then
I have just set up TrueNAS 12.0-U3 and trying to set up a one off backup to external USB drive on the same system, I think it's a replication task?
The UI does not offer setting up with USB backup devices, you will have to do some custom scripts to get that working.
@@LAWRENCESYSTEMS thank you
What a good April fools video 🤣
What is the diff between TrueNas and TruenNAS?
What do you use to encrypt your external sandisk?

Are you all using TrueNAS’ snapshot replication (zettarepl) successfully? I spent months trying to get it to work and just kept hitting bug after bug while trying to replicate ~40TB. I eventually gave up and switched to zrepl.
I use replication via the web interface and it works well.
