@ron @PinkCathodeCat @brennen @hairylarry sounds like you're in great hands with ron :) ill lurk.

@hairylarry

Yes. Mirrors provide data redundancy like RAID. You get more flexibility at the cost of storage. There is also RAID available in zfs called raidz as well. It is not recommended to build zfs on top of raid. ZFS appears to be better than hardware RAID at data integrity

@cosullivan they love telling stories... mostly weird hahahha 😂

@snowdusk_ I loved hearing "Ma Baker" too. These Boney M lyrics: "they killed him until he was dead" and "she knew how to die!" hysterical

@cosullivan haha it's my favourite Boney M. song! 😅 He has more really good songs

My earworm since @snowdusk_ played it on #aNONradio earlier this week. This video has it all: disco beat, bell-like vocals, dancing, shiny costumes and inane lyrics that made my preteen self double over with giggles:

"Rasputin" -- Boney M

@hairylarry

I would recommend sticking with mirrors though. They are easier to upgrade down the road. ZFS will grow automatically in to the size of the smallest drive in the mirror

@brennen @PinkCathodeCat @thinkMoult

@hairylarry
If you're interested in backing up your ZFS system sanoid comes with an application called syncoid that syncs the snapshots between ZFS pools. ZFS has an utility called ZFS send that allows you to send a ZFS snapshot to another zfs pool. This can also be done incrementally with "-i" which is what syncoid is doing.

@hairylarry @ron @PinkCathodeCat @brennen it sounds just fine in principle :) of course like all technical things the devil is in the detail. So maybe do a few small tests first! Im sure the folks on IRC can help too.

@hairylarry @ron @PinkCathodeCat @brennen sounds like you want ZFS. It does exactly what you're asking for. I rsync to a ZFS filesystem and then if anything gets deleted, I go back in time in the ZFS filesystem to get it back.

If you don't have ZFS you can do the same with rsnapshot.

In fact, you can do the same with plain old rsync and hard links. Hard links are amazing. Basically the file always exists until all pointers to the inode are deleted.

@Canageek

Yeah, I tend to think along the lines of the files system being the database and each file is a small data structure consisting of filename, timestamp,(title,content,links) where the stuff in () is the text and links might be filenames to parent files and comment files.

@samis @SDF

I enjoyed your post.

I am also a new SDF user. I went ARPA with the one time fee of $36. I was on a free but underused account for years (I forgot all about it). I am using SDF to store my public text files available from gopher or from a php web interface.

I'm hairylarry there just like I am here.

I set up a gopher site on SDF. Mostly song lyrics so far. SFF is scheduled to go up later today.
