RALUS dies in middle of backup, fails backup

Question

I'm using RALUS to back up our file server (RHEL 5) and every night the backup fails in the middle of this server reporting:

Unexpected end of backup set encountered on SONY 1. V-79-57344-34004 - End of data set was unexpectedly encountered.

I believe this error is being created because the RALUS process terminates for some reason (an issue I've never been able to resolve on this system). However, I have a script that checks to see if RALUS is running once a minute and restarts the process if it has terminated. However, this doesn't keep the backup from failing. My backups are to a Media Library using a single Sony TapeDrive for AIT4 media.

Is there a setting anywhere in BUExec for Windows Servers 11D that will allow the media server to tolerate a 1 minute disconnect of the RALUS agent or will continue to try to reconnect for a while before automatically failing the job.

Hi Andy,&nbsp;Not sure whether the problem still persists. If it does, have you tried putting the RALUS in debug and checking at what point it fails. Secondly, you can also increase the logging in Backup exec so that it will give you some idea as to on which file/folder did it try to backup last. You can get this in Tools&gt;Options&gt;Job logs.&nbsp;Regards&nbsp;DKN&nbsp;

Are you backing up deep directory structure?

Is that an option in the Linux backup settings because I am not seeing that anywhere to know whether or not I am. I am not following symbolic links or remote mount points in my backup. I'm not using any Open File Backup options. I'm doing a Full Backup using modified time and I'm doing incrementals - but both Fulls and Incrementals are failing on the verifiy only.

I have set RALUS into debug mode as suggested by the previous poster, but I haven't really turned up anything yet.

Hi Andy,&nbsp;There is no option in the the backup settings that will tell you about the deep directory structure. I think the backups of the deep directory structure (i.e subfolder below a subfolder below a subfolder, so on and so forth)...is a known problem in RALUS. The only way to know that would be to manually go through the different directories that you backup or enable a live debugging utility called SGMON on the backup server so that we might know whats causing the RALUS to cause.&nbsp; Secondly, during the verify process ideally BE does not goes to the RALUS (or for any remote agent for that matter) for anything, it should just do a CRC check on the destination.&nbsp;Regards&nbsp;DKN.

Well, I have enabled debug mode on RALUS and kicked up the BUExec logging options to the maximum in Tools --> Options. Additionally, I am looking for hardware errors in the event logs of my media server to see if this possibly an issue with my media or media library and not RALUS, which is quite possible. However, that wouldn't explain why ralus always dies during the verification process.

Thanks for your help, I will report back with what I find.
