Mind that these are ancient models that are dog slow for anything more than serving files. Not that they are fast in serving files...

I did the procedure on my (now 15yo) TS-410, mostly because the vendored Samba is not compatible with Windows 11 (I had turned-off all secondary services years ago). It took a few days to backup around 8TB of data to external drives. And AROUND 2 WEEKS to restore them (USB2 CPU overhead + RAID5 writes == SLOOOOOW).

Even to get the time down to 2 weeks, I really had to experiment with different modes of copying. My final setup was HDD <-USB3-> RPi4 <-GbE-> TS-410. This relieved TS-410 CPU from the overhead of running the USB stack. I also had to use rsync daemon on TS-410 to avoid the overhead of running rsync over SSH.

So, it's definitely not for the faint of heart, but if you go through the trouble, you can keep the box alive as off-site backup for a few more years.

Having said that, I have to commend QNAP for providing security updates for all this time. The latest firmware update for TS-410 is dated 2024-07-01 [1]. This is really going beyond and above supporting your product when it comes to consumer-level devices.
