CA Arcserve Backup - Exchange Backup freezing during daily backup

We are running CA Arcserve Backup version 11.1 (build 3202) on our file server. The exchange backup from our mail server is running the arcserve exchange agent r11.1 (Build 3200). Until recently exchange backups were completing ok but for some unknown reason when it comes to backing up anything on the exchange server the backup job just sticks saying it's "backing up files" but it isn't as I can see from the logs that it has stopped just shortly after 9.30pm the previous night.

What backup are you making? Full database backup or brick layer backup?? Also, did you check to see if the tapes aren't full? HJave you tried testeing with creating a new job just for backing up the Exchange database?? This way you can pinpoint the problem to either a bad backup job (which might be corrupted) or a problem with backing up your Exchange server.

I am making a full brick level backup and a database backup. I am also backing up the system state of the exchange server along with a few other disk partitions that contain data.
Tapes are not full - well over 80GB of free space on the tape. Also forgot to mention - if I re-start the RPC service on the exchange server the backup kicks back into life although it does miss out the current session.
We run two different backup jobs - one runs over the weekend and one runs during the week. Both jobs are the some except that the weekedn job does not eject the tape.
I suppose I could try running job to backup only the exchange server - do you think this should be the next step?

Commented:
I would suggest trying to pinpoint where the issue is.. It is either in the baqckupjob itself (what could be more than 1 issue i'm afraid :)) or with the Exchange server.. You said that the daily job does run and the weekend job doens't?? Maybe it is a corrupt CA job database (just a long shot thought, but you can never be to sure..)

Also, you checked the usual stuff like event viewers and Backup logs after tyhe job fails??

Both jobs are doing the same thing. If the database is corrupt what do I need to do to resolve it?

Commented:
First off start recreating a test job and gtry to run all jobs one by one.. So first the brick layer backup, then the full exchange backup, then the system state backup and check and see if any of those jobs hangs..

Also try to use a different tape, this way you can exclude  some things..

Ok, I will try that and let you know what happens. I will update you either later today or tomorrow morning.
Try to find RC of the issue. Divide the actual job like job for exchange DB, job for brick level and a job for system state and partitions.

Check if you find any error related to ESE on the exchange server event log when backup job is running

You can also run an NT backup for exchange DB and see if it goes fine.
check the number of transaction logs as if there are lot of them the job might end up enumerating the backup for ever. The reason could be that if the DB level is not full green selection at the storage group level.

If thats the case, I'd suggest enabling circular logging for a while which will play all the logs to the DB and then you can start backing up.

OK, I'm currently running a backup from arcserve to only backup exchange brick and database level.
ashwin - which transaction logs are you meaning. Where can I find them/what method do I use to empty them.
Circular Logging - what's this, where can I turn it on?

Backup of exchange database and brick level has completed - unsuccsessfully.

So it seems your ArcServe Database is corrupt or in use and doing something it should not be doing.. Do you have an option to restart the server?? Else i'd try and restart all ArcServe backup jobs on the server. Also, it looks like your Exchange server and brick level backup is working perfectly well.. After each beackup ArcServe will change and backup it's database, this database is used when you need to restore certain files. Did you check if your P disk is full??

Disabling circular logging does have some downsides btw. This means you can never ever do a point in time restore anymore.. The Circular logs keep track off all changes made to the Exchange database, circular logging means it will override those files.. I though you could find it with the properties of your mailbox store, it's a tickbox soemwhere inthere..
The files are normally located with your database of your mailbox store, just seacrh your machine for the .edb and .stm files and you should see the logs files, there are name E00000XX.000 (something like this). If there are a large amount of files there then circular logging is not enabled :)
