Making boot disk snapshots with Macrium Reflect
« on: July 08, 2017, 11:27:13 AM »
I hate RAID-0 and don't really care for RAID-1. I love making snapshots as  a way to backup the system.

Just installed 2x512GB "solid state" disks.  Using Macrium Reflect to clone them on a weekly basis. If you wipe out your data, or a virus eats it, you just boot off the secondary SSD and you are back in business. I do wonder if the virus encrypts all the drives on the system, or what. Maybe I should force the backup disk to be offline, I don't know.

 The secondary disk is always out of sync with the primary by a few days. The mirroring or cloning process of half-terabyte SSDs takes 25 minutes. This is scary fast considering the same thing on 300GB HDDs took hours. One time I logged 5 hours.

I think if I had RAID-1 and a sufficient number of disks, I would clone the disks anyway, so you have double protection. Mirroring *and* snapshots. Between the two, I will take the later.

I was tempted to buy this - are the clones really bootable?

I have Carbon Copy Cloner on my Mac which is absolutely bootable. There are very few packages out there on Windows that do this.

Believe me, I've tried it many times over the years.  Come to think of it, I will re-test it again. Last attempt was a week ago.

Good question... test it now while you still have a working primary boot drive and not in a crisis situation.

BTW, The cloning process has shrank to 4 minutes. It seems they must have made some changes to the software. It seems like it maybe does incremental cloning now. There is no way it can clone 512GB in a few minutes. So maybe it's smart enough to analyze the disks, see the delta and throw that on the target SSD.

SSDs are fast..

I  also run the clone process on HDD and it has shrank from 5 hours to about an hour. At the same clarity as SSD.

Yes. I've done recoveries with Macrium Reflect Free version and it works great. Very easy to do!  (which is super nice when you're sweating a recovery situation).

If you use the product regularly, I'd highly recommend the paid version. It's much faster. Plus you'll want to get into incremental/differential backups to speed things up.

(I'm only a very occasional user, that's why I only use the free version)

It's like a graphical  version of the "dd" command.  They put a fancy interface on it but at its basis, that is all it is. Copying the disk byte by byte.

Carbon Copy Cloner on the Mac does a full backup the first time and than only copies the changes. Have to say it works pretty dam good. I wish I had it when I destroyed my Mac when I upgraded from Mtn Lion to El Capitan. I also upgraded the memory, I didnt realize that the RAM was causing the machine to crash continuously. I didnt have the Mac diagnostic dicks but found a Mac utility on the web that did it and guess what? It failed the test, put back the old ram and the problem went away.

So back to Windows I understand what its doing block by block. I believe that the Macrium is one of the few Windows products on the market that is bootable. I know Norton ghost works as I use it but you have a separate Norton book disk. You boot from that and than recover the image. It works pretty good providing you dont have problems with the Norton boot disk.

I have been tempted to try Clonezilla but havent had time.

Hardware is worth nothing, it's the software /data that's worth everything.

I use SSD that do nothing but act as clones for the primary disks, and when I upgrade to larger, more expensive SSDs in the 2TB or 4TB territory, I will probably continue that  practice.

It's only a few hundred tokens per SSD module, not a huge deal. First World Problems.

Yeah, they are expensive but much less so than recovering lost data off  a crashed disk being frustrated.

Mirroring snapshots is my first line of defense, backups is the next.   Having experienced issues recently, I now take various factors into consideration.
