Huge incrementals with Ghost 15

After I updated to Ghost 15.1.0.36526, I am getting huge incrementals, to the point that they are sometimes even larger than the last full, even with little change happening between backups, which doesn´t make any sense.  I didnt use to see this behavior with Ghost 12, which was my previous version.  All along I have been using Diskeeper with the VSS-special setting set, to avoid any excessive unnecessary incrementals, and I had the same thing running also with Ghost 12, and I didn´t have this problem.  Now, my backup disk gets full after 3-4 backups, and have to delete everything to be able to do one more backup.

My schedule is one monthly full, and two weekly incrementals.  I wished I could do daily incrementals, but it is impossible with this problem.  In fact, now I can never get to the end of the month without deleting everything on the disk because of the huge incrementals.

Any thoughts on how to solve this?

jlua001,

That is interesting. Can you do screenshots of your Diskeeper graphic every day between the full backup and the next incremental. Maybe try daily incrementals over the next few days? I think you will find that there will be marked changes over the period. Let's discuss the situation after the next incremental. Can you post a screenshot of the Diskeeper graphic before the base image and before the incremental image?

jlua001,

Do you have any feedback for us?

Re: Huge incrementals with Ghost 15

I finally got to do the test over the course of four days: 1 base + 3 daily incrementals.  I took the snapshot of the disk file structure from Diskeeper right before each daily backup. 

I specifically was very careful not to do anything on this computer other than just checking email and use the browser.  I did absolutely nothing else.  The base was 246GB, and the three daily incrementals were:   79GB., 63GB., and 49GB, ranging between 20%-32% of the base.  The incrementals were smaller than the ones I see when I do them twice a week, when they can be at times close to the size of the base, thereby the problem.   Now, they are arguably still excessively large, considering that –as I said- I didn´t do anything other than checking email and browse the Internet during this test.

I tried enclosing the .jpg snapshots as attachments to this message, but I am getting an error.  Apparently, on this Forum, attachments can only be txt, log, or lue file types.  How do I post the jpg snapshots?

You can use the insert/edit image option in the editor to attach a screenshot.

Here are the screenshots of the file structure before each daily backup:

Before Base:

Before 1st. daily incremental:

Before 2nd. day incremental:

Before 3rd. day Incremental:

Re: Huge incrementals with Ghost 15

jlua001,

Many thanks for your efforts. We'll have to ignore (maybe) the Before Base screenshot as the System Files aren't present but each of the following shots are different (sectors moved) when they should be almost identical. As I mentioned earlier, this happened to me and it was due to Diskeeper.

Could you try this? Defrag with Diskeeper. Uninstall Diskeeper. Do daily incrementals for a few days and let us know the results.

In addition, the System Files shouldn't be all over the place like this. They should be in 2 or 3 blocks. Can you do an offline defrag with Diskeeper before you uninstall? In the Diskeeper report, does it mention a fragmented pagefile? Actually, there are far too many System Files in the graphics after the Before Base one. Something terrible is happening. Did you notice your Used Space in the C: drive was increasing.

Re: Huge incrementals with Ghost 15

I am not familiar with Diskeeper, but defragmenting a drive will result in extremely large incremental backups with just about any imaging program.  I have encountered this using other programs and have seen documentation on the issue.  I think Brian_K is spot on.  If Diskeeper is continually moving files around, each incremental backup image is going to be sufficiently different from the previous one to require a large file size.

SendOfJive,

Something weird is happening here. jlua001 has been deliberately not defragging since prior to the base image. Actually the screenshot Before Base is probably the only good one. The others show progressively increasing System Files that should not be present. They are accounting for the large incremental images.

Any news for us?

Re: Huge incrementals with Ghost 15

Just a quick update to let you know that Diskeeper seems to have acknowleged that there is an issue.  After analyzing some logs and system files, they have sent me a patch file they have produced to test on my Diskeeper installation, and I will be testing it during the next few days to see if there is a difference in the size of the succesive incrementals.  I will post here any results.

Accepted Solution

Re: Huge incrementals with Ghost 15

Here is the very latest update:

As I said on my previous message, Diskeeper acknowleged the problem, and sent me a patch/bug fix file.  The patch file, which consists on replacing the file "NsNtfsFSConsolidate.dll" on the Diskeeper installation directory with another one of the same name that they sent me, made a dramatic difference.  Differential backups with Ghost 15 that used to take hours and be many 10´s of GB´s., now take minutes and are an order of magnitude -or more- smaller.   Diskeeper tells me that they will incorporate this fix on the 2011 version of Diskeeper, or perphaps add it to an upcoming update to their 2010 product.

jlua001,

Many thanks for your feedback. That is going to help a lot of people.

I noticed this problem with Diskeeper a few years ago but I didn't notify Diskeeper as I assumed they knew about it.
