"The disk is full" message???

Greetings,
When properly configured, a task does have the ability to delete older back up images, or chains when the rules or quota (date, size, number of back ups) has been met. Improper configuration and/or not enough free disk space can interfere with this. If you'd like assistance, it would be helpful if you could provide:

OS
Version and build of Acronis
Size of your disk
Avg size of your back ups
The Task Type and specifics about its configuration (settings, number of back ups...) retention rules (example)

Determining which disk doesn't have enough free space is easy. You can look in Disk Management, right-click on a drive icon in "Computer" and select properties, or open the task for the job that won't run and see what destination you selected when you created the task. Typically these types of issues are related to configuration.

It is your drive I which is full and the cause is most likley all the tasks is the cause which point to this storage disk.

Your backup task "OS" shows having 318 tib backup files (505GB used) in one task. There is either a problem here or a good chance that what you have is listed wrong for both number and consumed space. I would recommend that you validate this backup to make sure what you have stored in this folder is usable.

If properly configured, the backup scheme can perform is own deletion of old backups which it creates. Listed below are 3 example which have automatic cleanup configured which will maintain a fixed number of revolving backups.

GH11. Create Custom Full Backup Scheme....Store/Keep 4 versions (chains). Use whatever number best fits the individual needs..

GH12. Create Custom Incremental Backup Scheme. ...Keep Full plus 6 Inc per chain. Store/Keep 4 chains. Use whatever number best fits your needs.

GH13. Create Custom Differential Backup Scheme. ...Keep Full plus 2 Diff per chain. Store/Keep 2 chains. Use whatever number best fits your needs.

GH25. Understanding differences between Inc and Dif for Safety

 Thank you, fellas.

I thought I had it configured right when I set it up back in 2014. I'll answer your questions, but first let me ask. I was trying to free up some space and got this error (see attached.) When I click "Knowledge base" it takes me to a generic web page that says, "There is no information about this error available now". So I'm stuck. I'm also really concerned now about the viability of my backups. If it gives me an error now, what if my drive crashes, will it also show this unknown error when I try to restore & then fail????

Anyway, here's the info you requested:

- Windows 8.1, 64-bit. Dell Desktop.

- Acronis True Image 2014

- I have several internal & external disks: See screenshot attached.

- I'm not sure how I would tell you the average size of my backups. I set it up to make an image backup of my drive C: (with the OS & programs) and then to do incremental backups of select folders on other drives (only stuff I want to save.)

- If you tell me where to get the configuration settings I will make a screenshot or just type them up for you.

- My OS backup that appears relatively large is probably an image backup of the drive C: with the operating system & programs.

Anyone?

I can't figure out what's wrong with it and Acronis tech support want me to pay $20 just to send a support ticket.

Your screenshots show that disk I does not have sufficient space for the backup shown whose destination is disk I. Follow Grover's guides to properly setup a backup plan to fit your needs and stop using your existing tasks. You should validate any completed backups you currently have stored and then determine which if any can be deleted. If deletion is needed do so from within the TI application so as not to confuse the apps backup database. DO NOT USE WINDOWS EXPLORER TO DELETE BACKUPS FROM YOUR SYSTEM.

How do I delete those old backups?

 OK, I guess I have to show what's going on. Here's a short animated GIF of what I'm seeing when I try to delete backups manually:

Also just on the side note, why is it only August 10th? It was suppose to back up that drive regularly.
