Which backup method?
So there are two primary backup methods provided in frontview, for purpose of backing up my volume data. There is the so called "File Backup" and there is ReadyDR. I'm assuming my machine (524x) su...
yea that is obviously there... What I meant is that the SMART mode has a more intelligent retention schedule where it keeps daily snapshots for only a certain retention period, then weekly, then monthly...all with different retentions, but the Monthly unfortunately is retained forward...I would like to make a retention policy that is just like SMART but doesn't keep monthly forever. I don't mind if I have to edit some config files or scripts somewhere under the covers.... is this even possible or am I stuck with only using one single retention that applies equally to daily, weekly, monthly?
I'll check out that other thread you did about all your customizations, definitely sounds interesting...

Honestly I never saw the point to the snapshot "thinning" that the "Smart" Snapshots do. Generally the oldest snapshot takes most of the on-disk space. And there's a reasonable chance that the older version of the file I need was deleted by the process. Plus taking snapshots even when nothing in the share has changed just creates clutter in the snapshot list.
I find that just taking snapshots when things change, and limiting retention works well for me.
But back to your question, there is no way to automatically thin the snapshots from the web ui. You might be able to do it by modifying the snapper config files (/etc/snapper/configs). Not something I've ever researched though.
I assume you mean check the box that says only create automatic snapshots if there are actual changes..
I see what you mean though if I have daily all the way for say 3 months or 6 months and its only snapshotting changes...then it still shouldn't get that big really, any bigger in size then if they are thinned out to weekly, whatever big changes are in there will been the weekly ones, etc. so it won't save any space, it would just theoretically simplify what you look at or perhaps mimic Time Machine in some way...but I take your point. Thanks for pointing me to snapper though I will check that out also.
ps - I should have brought this ultra2plus back into action a long time ago, actually I'm impressed at how well it runs basic stuff, no plex or anything, but its handing iSCSI and rsync like a champ...I mean with a large HDD in there I could create a number of iSCSI LUN's which are handy for backing up Macs or doing a better job of Time Machine then the way all the NAS's usually do it.

yes

If I recall correctly, the Ultra 2 Plus hardware is the same as the Pro 2. Fast enough to saturate a gigabit ethernet connection for basic storage. My Pro 6 is still in service as part of my own backup plan.
I haven’t been able to saturate the 1gbit Ethernet yet while reading or writing. I can with iperf3 net tests I got 117MB/sec. But I don’t know what tool to use to find out max reading and writing coming also through network, and anyway the new hdd I ordered will be probably faster then this cheap old barracuda I’m testing with now. Doing an iscsi based backup from a Mac through apfs file system over iscsi and doing whatever overhead involved in backup software etc was maxing out about 50MB/sec but I don’t think ultra2plus was the bottleneck. And that is still pretty fast enough.
CPU is barely sweating, I think the hardware is fine for this use, but I recall it struggling with plex transcoding back in the day and I don’t even do any crazy transcoding. It also could not handle crashplan back then mainly because of not enough ram, but it may have been os4 and 1gb I can’t remember now. It was one of the reasons I bumped up to the 524x with ram upgraded to 16gb ecc
