I donno, i would rather have a fully verified or compared one, and even in-so-much tested by having to do a recovery (which is dangerous in itself) . having 2 softwares would be to complicated for me, melt my brain. Program updates that make changes or cause failures, organisation of the backed-up elements, disk filling.
once again seperating the OS to a small partiton , and having it be small enough to easily store full recoveries , provides for more than one file item, in the case that one gets broken. Using sync and compare methods for "data" and the huge rest of it, visably seeing what is syncing (copying deleting and changed) prior to pushing the button.
Then compares, between the (data) backup and the other disk, tell you if things are chaging that should not be changing.
Is not so easy to do syncs and compares with running operating system, but easy to do with simple data.
Backup progams are going to handle all the files (take like incramental pieces, or database style backups) Then something goes wrong and the user suddenly needs to cope with all the parts and pieces created by the backup, and thatsa gonna suck.
So I like the backup file items to also be user managable, as depending on a program is not Yourself :-) and yourself is more dependable than a program is.
At any rate, If you ever have to Restore parts of it or all of it, and you then have to manage the file items the backup created, THAT is when you will wish that it was simple, and user managable.
Back one, database (big piles of files in huge chunks) can fail or fault. If your big ass data pile is in 2-3 places, but completly unchanged , not encrypted, not compressed, in the same folder structure. Then the user can access the files just like they did before. any single file , like say a bad picture, or a bad video, or a bad piece of music , is just one item lost. a f---up database is instead a complete horror show.
Ok delete all that, and say it like this instead. If your "Data" all your pictures and documents, and music, is on a different partition. And that partition is just raw file copied (synced compared) to an external disk (or 2) it is just as organised and managable there, as it was where it came from.
It is safer like that, because there is no program dependancy, it is easier to restore any or all of it because it is just a clone/copy of the other one.
