Incremental backups are nearly as large as the full they are based on?

If I do an incremental backup it usually winds being as large as the Full. The fact is that there hasn't been that much material added since the Full. Would appreciate any assistance. Running Ti11 on vista 32. Thanks

 

Do you defrag?
Are the INC and FULL stored in the same location?

 

Vista has the disadvantage that it is permanently busy with optimizing, sorting, etc.
For Ti these files are marked as 'changed' and will be backuped.

Under Vista the 'full-backup' is the best method.

You can search here in the forum (use the Search-Button) for other threads concerning this behavior...

EDIT:
e.g. Click

 

Yes on the defrag, Yes they are in same place. A question came to mind, when you select the full that you want to increment do you have to select the last .tib file in the series or will selecting the first file work. the reason I ask is that I just purposely selected the last file and it worked as it should?

 

A defrag will move things about and TI will see this as a change and back them up.
If you set up a scheduled INC, you can't pick the latest .tib file as it changes after each run. So I suspect selecting any file in the set should work the same as any other.

 

Something must be wrong with your Vista installation because mine doesn't continuously and permanently sort, optimize, and move things around. I schedule my defrags just before I do my weekly full backup. During the week, the incrementals are just a small fraction of the full image size.

 

@SloPoke
- autom. file indexing
- superfetch
- windows defender
- autom. defrag

These 4 points are responsible for moving files under Vista.

But: you can switch off all of them...

 

Thanks to all for info. Not sure what's going on, also have XP on machine and same thing has happened in the past. I misled a bit about defrag. I have in the past but not since last full.
