Have you used sanoid/syncoid? I started my ZFS journey with a custom script and then switched to syncoid/sanoid (and some much simplified scripts) for my backup needs. One of my use cases is for Raspberry Pis which seem to have a habit of becoming unbootable. These are Pi 4Bs running from SATA/USB SSD or CM4s using NVME SSDs. I have scripts that use
* dd to copy the boot sector (to a ZFS filesystem)
* rsync to copy the boot (FAT32) and root (EXT4) partitions (also to a ZFS filesystem)
* syncoid to copy the ZFS filesystem to another host.
This process runs daily. When a system craps, it's pretty straightforward to restore the boot sector and boot and root partitions and finally the ZFS pool.
I'm curious zrepl does that might be useful for me.
- ZeWaren 3y agoI don't need to backup my boot sectors or root partitions since all my systems are provisioned. I can always re-create them with scripts, should any of them fail. I'm only replicating the data filesystems. From what I see, sanoid looks quite similar to zrepl. Both tools are probably able to achieve similar results. I do feel that zrepl has more features so far, though. But hey, if your setup is working and your data is secure, that's the most important.
