I cant believe it so difficult to google this info... but I get LOADS of stuff about how to use Win 7 backup - but precious little on exactly whet the hell its actually doing. If anyone can help - or give me a link I would appreciate it.
I have Win 7, 64 bit Ult... and am current backing up to a NAS. What I would like to know is what it is actually doing (its damn inscrutible).
I have it backup once a week - and have a "system backup" and some other specific directories with my user data. It seems to create a "WindowsImageBackup" foldr which seems to hold the system backup.... thats about 37GB where my system partition has about 43GB of actual data... so I presume it not back up page files etc - so I guess thats a true "image" of my system partition? that correct? but it does not keep multiple backups... just th eone image - does it really take a full fresh copy each week - or is it cunning enough to update? Some weeks the backup does not seem to take long enough to do a full image of 37GB +.
Im more confused on the data backup - that has created a directory called <my PC name> and inside that has created a "Backup Set 2011-03-13 170003" which as you can see - it quite old... but inside has a further directory for each week of the backup. Are backups Diffferential or incrimental? as the size veries dramatically each week, I assume incrimental? but that means I cant delete any old backups
However, I messed around with partitions etc - and so today its now decided to create a new backup set "Backup Set 2012-02-12 170026" and the directory within it for this week is currently 30GB (and growing)... so I guess whatever I did has made windows think it need to start afresh...
So.. I would like to understand the backup phylosophy that Win7 uses.
and... Assuming I happy to lose ability to back any further than this week - could I delete the old backup set (dated 2011-03-13... its a total of 104GB and I dont really need anything but a "current" backup).
Thanks in advance for enlightening me
P.S. Happy if you want to guide me on sticking with windows backup - or go to something like Acronis True image
