I have to say these folks seem to be going all out to get you to try these.
I have tried 3 of them so far, and they do work.
Yeah i know they are not the full versions, but they do work.
I crashed my test machine and did a restore with their software and it did work.
Didn't crash it on purpose but I had a corrupted boot file,
can't remember which one. Could not get in to safe mode either.
Currently testing their beta system recover program-not on the list.
It makes a recovery partition like the others, called a 'capsule'.
Scheduling the number of backups and time frames are a little flexible.
Mine is set to one a week, one restore capacity. Or you can do one and leave it alone till you need it. Needs the recovery disk if you can't get the 'press f1 for recovery at startup, or you can't get into safemode or any other mode.
No drive letter unless you want to give it one.
Seems somewhat hidden like in the ones gHacks has listed work.
Hidden as in not looking like a standard drive or partition.
Easeus and Paragon's partition managers see it though.
It's not a fat or ntfs file system, something different.
Called a 'bc' backup capsule I suppose.
Only thing is, I don't believe my antivirus even knows it's there.
So that may be good or bad, I don't know.
Doesn't show up in 'My Computer'.
With Titan it was files as usual, this is different to me anyway.
Well that's the backup stuff.
The defrag takes a long time, as discussed before.
Still don't know the benefit of the low level stuff.
Which the backup does also, but doesn't take a day to do it.
I've been using these for 2 weeks, and learning.
So no long term experience with it.
But I like it. Just passing it on......
