Unable to run ISE Backup

Question

Hello All
If  I run a backup on ISE it fails with the Message of Insufficient disk space. Actually a dir shows plenty of disk space available.
Any Idea what problem it could be ?
Thanks Thomas

Thanks for your reply
We are runnig it on a 3355 Appliance
I found the Problem, the root filesys is on 90% :-(   Don't know what has caused this.
.....So next time doing a show disk instead a dir will help :-)
I guess I have to ask TAC to get the Root utility to gain access and to be able cleanup......
......or is there any other possibility ?
Thanks Thomas
