Howdy, I am trying to run a simple batch file before the full backup procedure that renames backups and deletes the oldest ones. It looks like this: cd /d x:\Timtest del old_2.tib if exist old_1.tib rename old_1.tib old_2.tib if exist timtest.tib rename timtest.tib old_1.tib The problem is that if I run the batch file manually - nothing to do with Acronis, it works perfectly, but when I run it in the "pre/post" options, either the backup fails, or it rewrites over the top of the timtest.tib backup. I have it working on another machine, and am trying to implement it on another and I'm at the point of tearing my hair out. When the backup fails, I get the following error message: Execution of user command Y:\Acronis.......rename_backup.bat failed. error code: 1 Acronis TI echo workstation with Acronis Universal Restore. WindowsXP Pro SP3. Any help will be greatly appreciated.
