Fullbackup of Acronis B&R10 doesn't run

Hi,

we've an Server running Acronis B&R 10. This server creates daily increment-backups and weekly fullbackups. The backups will be saved on an shared, dedicated hdd on an other server over gbit-network.

Some days ago, the fullbackup failed, because there was no free disk space on the backup drive.
We delete some files from the backup-hdd, and after some days, i checked the system, if the backups did run okay last days.

The incremental-backups runs perfectly without any errors; but the fullbackup did not run correctly:
The fullbackup starts, all seems to be okay,.. next morning, i check the status, and the backup hangs on - for example - 39%.
After 3 days of backuping, we reached 79%. The backup runs extremly slow.

We runned chkdsk on this server and rebootet it once or twice, but without success.

I would attach the SysInfo.zip (70MB) - but i can't upload more than 15 MB.

Any Ideas?
