Symantec Backup Exec and Acronis True Image Echo Server: Problems with parallel work

Hi!

We use Symantec Backup Exec 12 and Acronis True Image Echo Server for backup our Systems. Symantec for backing up on tape and Acronis for harddisk. We backup a Microsoft SBS 2008 System: Domain controller, Exchange and other database programs.

A few days ago I cloned the already existing Acronis tasks to have a continous harddisk backup for two weeks. From that moment on the Symantec jobs doenst work anymore.

The Symantec jobs start at 02:15 and the Acronis start at 03:00. The Symantec job works until 05:30 / 06:00 but they don't finish regularly. Only on Sunday the Symantec Job works fine, because on sundays we don't have an Acronis Job

Before I cloned the Acronis tasks both, Symantec and Acronis tasks, worked parallel. What has changed?

Thanks for Help
Simon
