Disk Full - Consolidating Archive

Thread needs solution

First I want to say Hi to all the forum guys :)

I wonder if someone can help me. I use TIH 2011. It creates a DIFFERENTIAL archive at shutdown. But Here is the problem... My first backup is around 570GB in size (the external drive is 1 TB). Then all the consecutive DIFFERENTIAL backups does not excede 20 - 100MB a day. I have limited the backup size to 870GB. But when the limit is reached, TIH tries to consolidate the archive and runs out of space. I wonder.. why it not just deletes the oldest DIFFERENTIAL archive? Does TIH have an option to delete the oldest archive instead of consolidation?

Thanx!

Consolidation takes a lot of space because ATI first creates a working copy of the backups it has to consolidates, works on them and if the operation is successfull, then erase the original backups and rename the updated working copies to replace them.

THis is why you are running out of space.

In general, ATI always complete a new full backup before erasing anything. I typically recommend to have backup disk space equal to 2.3 to 3 times the size of a full backup.

Deleting partial backups (incremental or differentials) doesn't work with ATI because of bugs.

Some alternative backups strategies:
- of course, buy a bigger or another backup disk,
- separate your system from your data, by having them on separate disks or partitions. Backup your system using a disk and partition backup and backup your data separately (see below),
- backup the data that doesn't change much (photos, music, movies) through file sync/replication (SyncToy, Karen's replicator, SyncBack, etc) and exclude it from your main backup.
