E000103E9:Failed to open the file Server1_17Sep07.tib for write: 262,161. Failed to start the backup operation. I've been receiving this error on two separate systems backing up to different media, I only have this issue when attempting to create new backup images from the command line, if I create a full-backup from within the GUI and then run the batch file, because the full-backup already exist it will successfully create the incremental. Acronis is called from the batch file using the following command; "C:\Program Files\Acronis\TrueImageServer\TrueImageCmd.exe" /create /incremental /filename:Z:\MyBackup.tib /harddisk:1 /compression:9 /progressff At one location, Z:\ is a mapped network drive to a NAS, in the other location I’m attempting to backup to a USB drive that is directly attached to the server. Any help would be greatly appreciated.
