Dylan Posted February 20 Posted February 20 I've a 4 bay NAS and am considering buying a second (almost the same) to serve as a backup device. Both would be wired on home LAN and running HexOS. The backup device would have greater storage capacity and slightly more RAM/CPU capability. What is the most efficient/automated way of copying writes to primary over to backup? My instinct would be to use schedule a cron job via rsync at certain intervals. However, I've also never used TrueNAS, prior to HexOS, and my ZFS administration was on production servers where backups were handled by a different group. So, what it be like? Quote
Mobius Posted February 20 Posted February 20 Well once buddy backup arrives that will likely be your best bet. until it arrives your best bet is checking out this page to see what makes most sense for you https://www.truenas.com/docs/scale/gettingstarted/configure/setupbackupscale/ 1 Quote
PsychoWards Posted February 20 Posted February 20 In Truenas under Data Protection there is an area for replication tasks, which is the preferred way to backup from zfs to zfs. 1 Quote

It looks like REPLICATION will likely be my preferred method as I DO wish to automate this. @Mobius Buddy backup is a GREAT approach for offisite backups and one I will use and ask others the same, I just want to automate my writes from primary to secondary in keeping with the 3-2-1 rule - the "1" being when buddy backups are implemented. I'm still at "2" 😆 1 Quote
Mobius Posted February 21 Posted February 21 ah i figured that buddy backup would work on same site too. Quote
