Symantec Backup Exec tape backups not writing replicated data

Posted on 2009-02-19

I just setup a new install of Windows 2008 Server Standard on a Dell PE 2850, installed Symantec Backup Exec Continuous Protection Agent (to replace Veritas Replication Exec) and Backup Exec 12.5 for Windows Servers. I use CPS to replicate data on a schedule from multiple servers to the local hard drive. Then I have a BE job to write this data to tape. For some reason it is only writing the folder structure up to the drive letter and then stopping, so all it writes is the server name folder, then the drive letter, but not the actual contents of the drives. BE thinks the job completed successfully because it got no errors, but only backing up 19,000 or so KB is certainly not a full backup.

After some experimenting I found there was a security rights issue on the folder I instructed BE to backup to tape and that SYSTEM was not even in the permissions for the replicated data folder. I added system to the permissions and applied it to all subfolders and files, then tried to make a tape backup again, which worked and I thought everything was good. But then when it tried to run on schedule later that day it did the same thing again, only writing the server name folder and their drive letter folders, but no contents. It of course thinks the job completed successfully.

I then decided to create a new replication folder and move the data there, this worked... when I manually ran the job, but then again when it tried to run on schedule it went back to only going up to the drive letters. So I then re-applied all security permissions, but that didn't work. I then tried changing the drive letter from D: to E: and trying again, but it's not working. I re-applied all permissions again, but still no go. I have no idea what is going on and why BE won't write the data. The user account it is using was successful on system access tests.

Does anyone have any suggestions or knows how to fix this?

    You need to backup the CPS data from under the CPS PROTECTED RESOURCES icon and not from any place else.

    Also CPS does not backup following mount points so first ensure that the data is being backed up with CPS properly

    Well I spent some time on the phone with a Symantec tech who apparently was not aware of this option because we found that the CPS services had to be shut down in order for BE to write the data to tape.

    I didn't see the CPS Protected Resources backup option before though but it looks like it's designed for what i'm trying to do. I've tried a manual job setup to backup the CPS protected resources and it worked. I want to make sure it works on schedule though first. It's weird though the backup that pointed to the replication data folder (rather than the CPS protected resource) worked fine on manual to, at least the first time around and after the first security permissions fix. Regardless I don't know the ins-and-outs of this software enough to know exactly what was going on and why I had problems the way I did.

    Anyhow I'll try this and if it works then that's it and i'll accept your reply as the solution.

    Thanks for the help!

    That was indeed the solution... Thanks for the heads-up on that one.
