I am running Arcserve 2000 and my differential backup is crashing. I disabled verify thinking that would resolve it and it still crashes. I looked at the log and the log is full of warnings at the end of the backup, they are AW warnings saying that the file has changed since the backup. What would cause it to crash? Also we use Backup manager for open files and I keep getting a warning that the 'Preview size has been exceeded', what does this mean and could it be related to the crashing? I am new to Arcserve, I am a Veritas user. If anyone has any links to any tutorials that would be great. Any ideas?
