znapzend backup generator script

[PretoX]

Hi guys,
so everyone who uses proxmox on zfs probably knows that pve-zsync is not a best tool to make backups (no sudo, mbuffer and gzip etc) and you have to modify script after each update. And I also saw topics about znapzend tool, but you have to make separate task for each zfs dataset and manually copy the config file which is not a bit task but still I wanted to do it faster.
So I made a small script to auto-create all znapzend jobs and to backup config files during initial vm/container backup configuration. Hope this helps to anyone. And maybe some improvements appreciated.

Topics to be reviewed to get familiar to this backup tool:

I'm using znapzend to replicate my backups to remote sites, which afaik is not possible with PVE Replication.
Very good indeed. But there can be conflicts with PVE replication...

How are you monitoring your backups? I''ve looked around but found nothing about.
It could be very usefull an email alert if the job fail

would this work on proxmox 5 and 6?

I have znapzend running on pve 5.2 but see no reason why it shouldn’t run on pve 6 as it’s using standard ZFS features and commands.

Good work.

Hi PretoX,

In your script where / when do you notify actions using email variable you have ?

I have tried znapzend but i could not get it to work, what im trying to do is backup vm to another usb external disk but cannot get it to work.
this is my setup but not sure if im doing it correctly

znapzendzetup create --recursive --mbuffer=/usr/bin/mbuffer --mbuffersize=1G SRC '2d=>1d' rpool/data/vm-125-disk-0 DST:a '14d=>1d' usbbak
