Backup Location out of space?

Thread needs solution

I have a 450GB harddrive for my backups. I created a backup location and set the quota to 350GB. This morning the backup failed with the error that there is no more diskspace available. I thought the function of the backup location is to manage the backups and delete older one's as required to make space for new one's. Have I misunderstood something or is there another problem?

Thanks for any tips or suggestions.

It is possible that ATI is trying to do one more backup before deleting a previous one. ATI will always first do a new backup, then delete older versions.

So if your backup is 200GB, set up as full backups, and you request ATI delete older backups when space runs out:
- your first backup takes up 200GB,
- ATI tries to do a new full backup, but is left with only 150GB: not enough space.

If you had 500GB,
- your first backup takes up 200GB,
- the second one takes another 225GB,
- then ATI deletes the first backup.

Thank you for replying. The backup scheme is incremental so it shouldn't be a problem. The backups everyday have only been around 10-12GB. The one is was trying to create yesterday was over 100. I'm not sure what that was. I didn't accumulate 100GB's of files the previous day... I deleted the 100GB file that it was trying to create and lowered the backup location quota by another 100GB. Now, ATI will get up to 98% complete on the backup but never finish. It produces the normal backup but it seems to be stalled trying to write a file that looks like this: D0C7851F-9EFA-4CB4-B866-3840F2F2FE63FDP1. None of the other files in the folder look like that so I'm not sure what that file is or why it won't finish writing it.

My next thing would be to check the disk for file errors.
Chkdsk c: /F

Is this a partition backup or is the files and folders backup? There have been reported instances of bad files preventing a backup from completing.

The file name you describe is a temp file--normallly removed but didn't.

Jereme,

This is a high chance you confused ATI when you deleted the backup it was trying to do. If I were you, I would start a new task in a new directory, and I would delete the older backups when they become old enough.

Are you using autoconsolidation by any chance?
