New full backup created? Why?...

Thread solved

I've got my settings to not create subsequent full backups:

but last night it created a giant, seemingly new full backup.

But why?...

Eliezer, your screen image only shows one Full backup followed by a series of 6 differential backups based on the initial full image.

Given the size of the 6th differential, it looks like some major changes have occurred in the period singe the initial full was created, hence it looks similar in size to a full backup file.

Have you done a defragmentation of the source drive recently as this could cause this type of size increase?

Was wird denn im "Aktivität" Tab angezeigt?

No, no defragmenting or major changes at all. Since it's set to differential, will each subsequent week from now on be huge like that? (If so, I'd probably just opt to start a new full backup again to avoid giant, long-running backups. But I don't get it.)

Here's what the activity tab shows:

The activity page is confirming the large new file is a differential so further backups will be of equal or larger size as it is always a comparison based on the initial full backup image.

That's exactly what happened to me with my 2 HDD.

Both backups started doing a "-0001" version of them. 
They were full versions, they took over 2 hours to make the backup, and they both were over 550GB size. 

After a couple of weeks my 4TB HDDs have around 2.5TB left with, supposedly", one 550GB backup.

Is this "new bug" (?!) due to some kind of update? 

I've got ATI 2020, Build 38530

Hello, 

I do not know, because I just bought those HDDs 3 weeks ago.

I just want to have full backup of my laptop, with incremental changes because sometimes I need old files that I have changed.

The old WD Backup tool made a 2.5TB backup with incremental changes in 2-3 years. I would like more or less the same with this tool.

 

Harold, this confirms what I suspected from your post in the ACPHO forum. You have set for 5 increments so after those are created it will produce a new Full backup with a new number on the file name.

Your cleanup rules are now set to delete versions over 183 days. Since you will have one new Full created every 6 days, you could potentially have 31 chains which would take a whole lot of space. I suggest changing the cleanup rules to store no more than X recent version chains... X being some number you are comfortable with.

Thanks Bruno, 

 

I understood those "5 increment versions" were for the individual files not the entire backup. So I will try with the "Create only incremental..."

 

Thanks.

I agree, way t o many chains in your scheme.  Further, you should probably change from an Incremental Backup scheme to a Custom Backup scheme leaving the Incremental Method intact but changing the chains to something more reasonable.  I myself only keep a maximum of 3 chains.
