Increments of disk backup are unreasonably LARGE

Thread needs solution

Hello!

   My usual practice is to store one year+ history of my system disk image backups, made with new full image every month, and little daily increments. From time to time, I have to restore full system via "offline" method (because of its fastness, simplicity and completness). My system consists of number of SSDs combained in one drive by hardware RAID card by LSI, which contain ~600Gb of data at 2Tb partition “C:\”, and hidden boot 500Mb partition made by windows. Full image of this drive (with compression) usually weights about 500Gb, plus increments form 500Mb to 1Gb or 0,1% of total data amount. At least those sizes (and percentages) is my statistics for “Veritas (formerly Symantec) System Backup” for many years that I’m using this software.

   Now, when I setup Acronis True Image (2017) with such scheme it makes a full backup system drive image almost the same size as Veritas, but daily increment has an incredible size of 100Gb, a hundred gigs daily!!! It is 1000% more than my usual increments.

   Then I made an experiment: made new incremental backup task for disk image in Veritas and Acronis, started it and in 10 minutes after completion run backup task again, so first increment appears. I’ve got same results, Veritas made ~200Mb increment and Acronis made 60Gb one! I’ve wait another 5 minutes and run backup task once more, and all repeats, 200Mb by Veritas and another 60Gb by Acronis! What in a world is changed on my drive for those 5 minutes that Acronis put in a 60Bb increments?

  Or I’m doing something wrong? Please help me with this issue.

 

With kind regards, Alexander.

Alexander,

Welcome to the Forum.  Wow, I have never seen a post like yours, in fact, you are the first I've seen using an LSI controller running a RAID array for a system disk

My thought here is that there exists some incompatibility with Acronis and your LSI controller.  I would suggest for you to go into the help section of the GUI (question mark lower left of screen). and select the Send feedback option.  Describe your  problem and even make reference to this thread if you like then send it off along with a system report which will be generated by default by the feedback tool.

The support team will get this feedback and should contact you about the issue.
