Personally, I have 4 backup file servers. They are powered off expect when actively doing backups. If one gets corrupted, I have the other 3. They are all running linux and use mdadm raid 5.

Same, except my backup servers rely on ZFS. Thanks to COW there is no question what blocks/files have changed and "incremental" backups are a matter of seconds vs. minutes.
The machines turn on automatically on a schedule and turn off after completed backup. This lowers exposure to compromise, but more importantly (to me) saves $$$ on the power bill.

How do you manage the on/off?

Since the last deal was pages ago, probably time to start a new thread with the next deal.

The cheapest and easiest is in the UEFI/BIOS power management option. i.e. boot computer daily. There are software packages which can be used to set/update the time of day.

You can use programmable IoT outlets and boot the computer from another one.

I have a "switched" PDU which is the lexus option to power on/off computers over a network.

... and yes, IPMI works, too :p

like ca4y6 said, ipmi.

I have a script in TrueNAS scheduled to turn on my backup server via IPMI periodically at night to replicate snapshots.
Helps me keep power usage down and provide me with some protection against hardware failures and ransomware if they somehow end up removing or encrypting all snaphosts on my main storage.

This is what I do too. Main nas is 4x rz2 6 wide. Every 18mo the "smallest" vdev gets totally replaced with what ever id the current best $/tb sas on the used market. Extra disks replace whatever is smallest in the 2 backup nas (one local, one remote) that are 3x rz2 12 wide with no consideration for size in vdev matching. Backup machines are powered up and down via ipmi, remote unit has opnsense + tailscale on it... been working well for years.

Prices are absurd right now. In late 2017 I bought a pair of SN200 7.68TB drives for around $350 each. In 2023 I bought several 1.92TB drives for like $90 each.

The best "deal" I've seen is a pair the OEM equivalent of a 960GB Samsung 840 for like $70, but those have poor performance and there was no SMART report.

Seems crazy expensive to me :oops: .

I could get 3.84 TB for less than 100 EUR a few Months back (SATA, not NVMe though).

In my humble opinion smaller drives are a very different product and price category. Also, prices a very months back probably don't mean much in 2026.

Anyone finding deals <$100/TB for 8+TB drives has a bargain.
