Hi, sorry for the late reply but I've found these articles really useful. Mostly got those by searching this forum and the web. https://pthree.org/2012/12/04/zfs-administration-part-i-vdevs/ https://blog.victormendonca.com/2020/11/03/zfs-for-dummies/...

You should make use of vSwitches and get 10 Gig Ethernet switches. Would recommend Mikrotik switches. Unify is a waste of money to be honest, so those hundreds wasted on Unify could be re-allocated on your actual server and it's I/O. If you got money to waste, donate to the poor & hungry. Learn...

This will help you big time concerning the ZFS file system: https://www.truenas.com/community/resources/whats-all-the-noise-about-hbas-and-why-cant-i-use-a-raid-controller.139/ https://forums.unraid.net/topic/102010-recommended-controllers-for-unraid/ As far as I'm concerned, the layout which...

If the receiving back-end is just pure storage, then I can recommend doing this. 1) Get x2 decent 50G SSDs, or w/e SSD you have lying around - anything will do tbh - Assuming /dev/sd[a-b] 2) 2 partition of type ZFS Solaris: 1 for the zil slog (5% number #1 sda1), 1 for the l2arc (95% of total...

:D:D:D read: IOPS=26, BW=107KiB/s (109kB/s)(6488KiB/60811msec Fio does what's it's being told to do What kind of CPU do you have ? Why are you giving an io depth of 64? A sequential job with iodepth=2 will submit two sequential IO requests at a time. Why are you testing with the libaio...

The other way would be to directly modify the /etc/cron.d/vzdump and add the --script to that specific backup job and then hope it doesn't get auto magically regenerated. Or modify the vzdump script directly, if you can perl and got time Don't RIP your backups ;)

I have no other choice my backup size is 15G into a usb stick of 16Gb capacity or something along those lines :D Either way, I solved that problem by using the hook feature of vzdump. Fortunately the vzdump utility calls the hook scripts with a bunch of parameters such as: INFO: Hook called...

Good morning :D I would like to setup a backup task where the vzdump archive file is pruned before the actual file get transferred to storage INFO: 100% (15.0 GiB of 15.0 GiB) in 27s, read: 1.2 GiB/s, write: 6.7 MiB/s INFO: backup is sparse: 13.31 GiB (88%) total zero data INFO: transferred...
