Like I already told you (PM/chat): Provide more info. What kind of storage? Some consumer grade NAS? Huawei? EMC? NetApp? vSAN? We need to know the brand and model, everything else is just wild guessing on our side.

And by checking, he means learning and just happening to find it.

Red Hat has introduced a new technology, called Stratis, that is a layer combining Linux' existing LVM2 technology and the existing XFS filesystem and merging them together to be managed as a single unit with best practices automatically applied. It's not new per se but takes best of breed existing technologies and puts them together to feel and act more like their more modern competition.

Easy enough to add to XS7 I assume, but sucks that it isn't the default.

My situation wasn't a snapshop - it was a fast copy.. so I'm not really sure.

I just used this myself to make a new block device in a single line. Awesome 🙂

LVM is awesome, it is a great tool.

I use it all the time. Snapshots are awesome. I've just never needed to use multiple disks and didn't think of the above scenarios when you would have multiple PVs.

Anyways, i won't lose the joy of using xen as i just upgraded my home server xen and added XO 🙂

LVM clearly dictates.....

Best practice, which almost no one follows, is to use explicit paths in scripts rather than implicit. then you don't need that at all.

I guess that makes 100% sense since you have to start the script with an absolute path ha.

I like the sound of it as well. Hopefully it will be recorded too.

It really does work most of the time. It's difficult to make a plug and play, one size fits all product for business computing. Every environment is unique, and every admin has their own methodology to configuring their architecture (often, that is driven by general cluelessness and/or ignorance). I think that, given the diversity of what you have to be able to adapt to, the roughly 95% success rate that I have seen with incremental forever is pretty decent. The thing that makes it somewhat aggravating is that it is a proprietary mechanism that is held rather tightly. Even inside of Unitrends, there doesn't seem to be a lot of general knowledge floating around about how to fix it when it doesn't work. The algorithms that control it are basically "unknown". It's a magical thing, powered by pixie dust, and you don't mess with it; it just kinda does its thing. If you have a Unitrends support contract, and it's giving you trouble, they can help diagnose it and get it fixed. For the rest of us...

Only complaint would be that for a backup system, 95% success rate is way, way too low for it to be a recommendation. It should be a "this is really fragile but if you want to give it a shot and monitor it closely, here it is" kind of thing at that point. It's a neat idea but if it doesn't match the reliability of traditional setups, I'd think recommendations should fall to the reliable. No aspect of IT has a stronger leaning towards consistent, conservative and reliable as backups.
