    Recursive rollback? Am I asking the right question?

    I've used the rollback feature to go back to a point in time for a specific dataset. No problems there. If I create a recursive snapshot of an entire pool (all child datasets included), it creates a snapshot for each child dataset within the entire pool. So far, so good. Yet if I rollback the...

    FreeNAS Disk / Backup setup options (moving from WHS 2011)

    Hi All, I'm in the process of testing FreeNAS as an alternative to my WHS2011 - I've reached the 2TB limit on it and need something to replace it. This is for a home system for photos, music, films, ISOs, etc, and some data. My current WHS setup is effectively: 2 x 2TB disks in mirror (using...

    Snapshots and used space

    I needed to clean up some space, because volume has hit the 80 %. So I started to delete a lot of large files, which I didn't need any more, like large downloads etc. After that I noticed, that little to none space was freed through this. So I thought about snapshots. Listing the snapshots in...

    Confusion regarding Replication Tasks

    I'm attempting to set up my replication tasks on FreeNAS1. The Snapshots run between 0630 and 1830 then stop. Then my replication task starts at 2030 and I end it at 0530. So on FreeNAS2 I get ALL these 15 minute interval snapshots. But since FreeNAS2 is my offsite, I really have no use for...

    Backup/Dataset replication with zfs send/receive
