Small Disk Backup Strategy
I have two computers in different locations. Without going into details, one of them has only a 500Gb disk available for imaging backup, with 360Gb to back up.
For the moment, I cannot buy a larger disk. I need to back up every day but do not need a backup older than four or five days, so backups can be done on a 4 or 5 day cycle.
At the moment every clean up strategy I try ends up with a disk full failure after a few days.
Can anyone suggest a blow by blow way of achieving what I need without manual intervention?
The lack of storage space is truly the issue as indicated by MVP shadowsports.
In your situation, a full backup will only succeed if there is NO OTHER BACKUPS, or your storage disk must be empty of backup files before any new FULL backup will succeed.
So, you must either delete the old backups youself either manually or write a batch program to do the deletion.
There is a helper program called Chain2Gen which will do this for you if you wish to pursue in more detail.
Click my signature link #1 and find the Chain2Gen references in item #5 inside my links.
What C2G will do is to perform the deletions in advance of any full backup which is your problem due to space limiatations. You are getting the disk full message because TrueImage will attempt to create the replacement full first before it will delete the old chain and you do not have enough space for 2 fulls even for the few needed seconds that both fulls would exist.

Aha! That's the problem then. I had thought it would delete first but on thought I can see the logic.
I had thought to get away with it since I don't need more than three days of backups on what is a second machine.
Thanks, all.
If using the incremental type backups, you might be able to let you incremental backup accumulate for 2-3 weeks before you need to start over.
My major point was that your full backups can only be succesful when the 500gb storage disk is empty of backups.

Yes, understood. That explains my problem - I guess I'll really have to get a bigger disk in the light of that. Thanks for your input, much appreciated.
