I have been trying to do something which used to be easy and has been a problem, of late. I have been always keeping backups (sometimes more than one) for most of my computer career. I have reached a situation now where it has become increasingly difficult to find a package which does what I want.
Namely, I want a backup made of specific directories and/or files which incorporate only the changes that have been made since the last backup. I would like this to be in the same format as Windows Explorer, although I am begrudgingly willing to take a look at packages which create backups as zip files (which have to be opened and scanned to find any files which I am specifically looking for). By the way, I am running in a Windows 7 operating system
I thought I found the program which would accomplish what I wanted (see above title); however even though I have selected to run incremental backups only, it runs a complete backup as a zip file every time a backup is run. This has resulted in quickly running out of space on the backup disk drives where I have the backups.
No matter how much I investigate and read about the program I have, although it implies it could do what I want (details to follow), it seems to do a complete backup and save it along with all previous backups (approximately 300 GB each time). What I want seems simple to me: if I have 1000 documents, of which I make changes to 6 documents between backups, only those 6 documents will be updated in my backup.
Is anybody familiar enough with the above title backup software that they can explain how I can set this up properly; or-an alternative backup software program which does what I want easily? Thank you very much for your help and suggestions.
