I have searched all over for this but found nothing... I just started running Active Backup for Business on my DS-920+. After reviewing the folders and contents of the backups with Windows explorer, every backup appears appears to be a complete backup of my PC. Can anyone point me to how to make subsequent backups as incremental ?
Check out Deduplication and Versions. Together they are your answer, they improve upon and replace
incremental.
With deduplication, the file exists one time, but can be seen/applied from many ways. Assume
Entire device backups of three identical computers all running the same lock screen background. With deduplication, there is only one copy of the lock screen background file taking up storage space, but all three devices can be restored from it and it will show as being there for each device. Incremental would have saved three copies of this file, one for each machine. The only real issue with this is that File Station does not properly report space
actually taken by files that are deduplicated, it shows the size as if all three files were present when only one is. AB
fB shows the actual space and the approximate reduction ratio.
With versions, the file exists in it's original form plus
the changes, versus incremental having the original, then
replacing it with rev-1, then
replacing it again with rev-2, etc., each time replacing the whole file. Say you have a file with 80-lines of data and 2-weeks after backing it up you change line-14 of that file. With incremental, the old file is overwritten with the new file. But what if you need the old file with the original line-14? Unless you have multiple backups going back far enough to grab it you're out of luck.
