Check your snapshot management tool's manual on how to use it to automatically send snapshots to a backup source. Let’s talk about mirror vdevs, RAID-Z or dRAID to better understand real redundant data storage. For example, Sanoid (mentioned above) has a replication tool called Syncoid that can work with Sanoid. Setting up a ZFS pool involves a number of permanent decisions that will affect the performance, cost, and reliability of your data storage systems, so you really want to understand all the options at your disposal for making the right choices from the beginning. TrueNAS SCALE is Linux based, still in beta at time of assessment (edit: very recently out of beta. TrueNAS, officially supporting OpenZFS, backed by iX systems. Ubuntu, officially supporting OpenZFS, backed by Canonical. Many ZFS snapshot management tools either contains, or works well with replication tools. Here’s the summary of options after asking people for options in that thread. Every time ZFS reads a block, it compares that block to its checksum and. Just like taking snapshots, sending snapshots can also be automated. Okay, so all jokes aside, ZFS scrub is the best way to handle the dreaded bit rot. See more on this topic on zfs-recv.8 and zfs-send.8.Ī common way to do backup in ZFS is to periodically attach a backup drive (or a drive array) and send the latest snapshot to the backup ZFS pool on it. for files when when all the read/write/checksum errors were at zero. There are many options on using zfs send/recv. Solution 1: Scrub your pool again (if you havent already): zpool scrub zstorage. This allows us to reorder I/O in such a way as to achieve near sequential resilver throughput even with limited memory resource usage. Zfs send source/ source/ | ssh remote.ip zfs recv backup/dataset The scrub examines all data in the specified pools to verify that it checksums correctly. This talk discusses some forthcoming work for OpenZFS, where we have achieved performance improvements on resilver by implementing an intelligent block sorting pre-scanner ahead of the regular resilver repair code. # To send incremental data between snap1 and snap2 only Zfs send source/ | ssh remote.ip zfs recv backup/dataset # To send a snapshot to a remote pool (at remote.ip) via SSH With Linux and ZFS, QuTS hero supports advanced data reduction technologies for further driving down costs and increasing reliablility of SSD (all-flash) storage.Zfs send source/ | zfs recv backup/dataset In addition to the manual zpool trim command, a background automatic TRIM was added and is controlled by the 'autotrim' property. QuTS hero is the operating system for high-end and enterprise QNAP NAS models. Since mentioned by the developer from openzfs. WIth Linux and ext4, QTS enables reliable storage for everyone with versatile value-added features and apps, such as snapshots, Plex media servers, and easy access of your personal cloud. ZFS has and Event Daemon (ZED) that monitors all ZFS events (such as a scrub being completed) and sends an alert email. QTS is the operating system for entry- and mid-level QNAP NAS.
