How can I delete differential backups?

I am using ATI v11 Build 8,053, Vista Home and backingup to Acronis Secure Zone on an internal SATA disk (not the OS drive). Following a full backup I do a weekly Differential backup. The current size of the zone is 117 Gb and there is no more space on the drive to increase it.

I understand that only the latest differential backup is needed for restore but I can't find any way to delete the older ones.

I have checked through this forum but I can't find an answer and would appreciate help to resolve my problem.

 

Hi Halsgrandad,
I think you're confusing differential and incremental backups.
Differential backup creates only one file and therefore cannot be deleted.

On the other hand, incremental backups create as many files as you increment,but there again they cannot be deleted as they are all needed to successfully restore your OS.

 

Same problem, although I don't use SZ as it caused nothing but errors. So, even though I have a "managed" backup location, nothing is actually "managed" about it, and I have to manually delete differential backups as they build up. So much for setting a limit of 10, it simply ignores the limit. But whats new? Does nothing work right in this garbage?

 

As far as this goes

its simply not true, as they do indeed build up.

 

Differential backup are difrent from incremental backup by creating a new Differential file each time u made Differential backup , thats compare to the FULL BACKUP file

so I THINK U CAN DEL every Differential file as u want, as long u keep the full backup file (the big one)

 

OK, it appears that I'm correct in thinking that I don't need to keep all differential backups but how do I delete those I don't need?
Perhaps I'm just thick but I can't find a way to do it!

 

You can't delete files from the Secure Zone - that's why it's "secure".
See the last post here for TI rules on handling full Secure Zones.

Thanks for that Weaz. I missed that thread in my earlier search. It does answer my question. It might help if the information contained in the last post was included in the User Guide.

Thanks once again.

OK. I give in!
