Question about Incremental backup
Hi, I have ATIH 2017, I set a daily (mon to fri at 12.00am) image of my C: drive with the suggested scheme "Backup method = Incremental", with "create full version after 4 incrementals" and "store no more than 2 chains"
It works, so I see the Full backup, and the "incr." backup as expected.
Full is 50GB
BUT
Each Incr. is 1,2 GB
HOW is possibile that each day I change 1.2 GB since previous day? It is not like so. I don't change 1.2 GB of data.
This seems like a "differential" scheme.
thanks

You are backing up your C: Windows OS drive and there can be many more changes involved than just the things that you change in terms of user data.
Some of this will depend on what Exclusions you have configured (or accepted if using defaults) for the backup task?
I would suspect that if you performed an Incremental backup after only a few hours, you would also see a significant amount of changed data. Programs like Antivirus / Security will do daily updates (mine checks for updates every 6 hours!), Windows may do 'maintenance' tasks daily which can involve some defragmentation activities.

Is there a tool to see the difference between two incremental backup?
say I have a full backup + incr1 + incr2
I want to see which files are modify/added in incr2 respect to incr1

Sorry, there is no easy method of identifying differences between two incremental backups, especially for Disk & Partition backups as this works at a disk sector level for identifying changes.
