Man, this is so greatly organized introduction to TrueNAS. I watched like 50 videos about TrueNAS, I heard a lot of these terms related to it and I was so confused but you have finally explained it all in an clear and organized manner, thank you!!!
Long winded answer...my channel audience is a bit split and so some videos have been struggling. This video was not doing well for a long time and so my priority for the next video on TrueNAS was low. This video has shown a lot more interest recently so I will for sure move it up the list. I have a few others first but will then pick this up again!
You don't loose all your information from updating the truenas system as far as I know , unless you are possibly have a crash while updating ZFS features, the data disks can be moved to different systems. if you use encryption you should have the keys backed up though
Correct, you don't lose your data when updating TrueNAS. I was just mentioning that when you update the ZFS file system then there is a small risk that there could be a bug in the update that leads to data loss (there was an instance of this as early as last year), so having your data just on 1 system is always a bit risky and wise to have a 2nd TrueNAS instance or Cloud backup etc. And for sure you're right that if you enable encryption (which you generally should) then make sure your keys are backed up in multiple places too!
ruclips.net/video/vDcYz3a21TA/видео.html This scenario will not benefit from a slog device. It depends on whether the writes are "asynchronous" or "synchronous". The latter are helped by a suitable slog device. They typically occur with a hypervisors which store the virtual machines' files on the NAS, and with database systems when the files of the database are on the NAS.
Yes, I should have mentioned synchronous versus synchronous. However, in my scenario of having lots of users saving files I would expect most businesses to want to be in synchronous mode to prevent data loss. I personally use synchronous for all my data because if I've got to all of the effort to have backups, snapshots, 2 instances of TrueNAS etc then I might as well reduce the risk of data loss in a power failure scenario too. It's all a risk / performance trade-off really and depends where you sit.

Your nice comment is really appreciated! Thanks.
Currently researching for work and home and this video is truly helpful. Thank You, subbed for sure.
Great guide - very clear, to the point and covers a vast range of factors to consider!
That was really interesting, thanks for sharing this wonderful video.
Very helpful video. Thank you
Thank you very much for the video. Any idea when will you have the next video in the series about installing TrueNas?
When would be next promised video on TrueNAS setup?
