Syncoid To usb retention policy ZFS?



  • Hi,
    I was wondering if someone could shed some light on the issue im having, currently trying to backup my vm using ZFS
    currently using syncoid to backup to a usb which i have accomplished by this command

    syncoid -r rpool/data/vm-125-disk-0 usbbak/vm-125-disk
    
    

    the issue is that there is no retention policy something like to keep 4 days or so 4 snapshots. i checked the manpage does not say anything about retention any ideas?

    Thank you



  • syncoid is an under the hood tool of sanoid.

    You need to configure the parent tool for what you want to do.

    What is the contents of /etc/sanoid/sanoid.conf



  • Thanks for the reply i did realize something was odd, i did configure the sanoid.conf but was taking the snapshots within the server and not sending to the USB drive
    The idea is to take snapshots every day and keep around 4, what im confused on the daily = not sure if its to take 1 time a day or delete after 1 snapshot? and as for the cronjob i have noticed it does it automatic even if i dont put it in the cronjob?

    Thank you

    Do you want to keep 4 dailys. So daily = 4



  • Thanks for the reply, the issue is that sanoid.conf does not send the snapshot to the usb but syncoid does, or does having that template automatic prune the snapshots?
