I know a lot use Acronis backup -- I've been using it for ages and never had a problem with it
However there is a defect (actually missing feature) in it that has a serious implication for Winsows 7 Users.
1) Say you have define a picture library.
2) imagine in the pictures library the folders are defined similarly as follows d:\pics1, e:\pics2, e:\subfolder\pics3, \\networkdisg\z\pics4
3) You now want to run a backup of DATA (not image / partition).
4) The Acronis menu presents a list of DISKS / Computer etc but no LIBRARIES.
This means that you manually will have to remember every folder that your library has within it so you can back up the library reliably.
This rather goes against the whole point of Libraries as the purpose is not to worry where on the physical disk the data is actually stored.
The built in backup with Windows DOES work with libraries for data backup - but you lose the other things a nice fast commercial program like Acronis has such as Incremental backup, compression, multi-media spanning etc etc.
I hope Acronis addresses this .
I don't think Macrium or paragon can back up libraries either.
I like libraries -- but I want to be able to back them up properly as well with my normal backup program.
