Extremely Urgent! Backup not working, disk space running low due to transaction logs not flushing

Our tape backup drive has gone kaput and we won't be getting a new one until next Wednesday.  I wish they would have diagnosed the problem sooner but they didn't and now we have not have a successful backup since last Wednesday, the drive space is dwindling due to the transaction logs not being flushed.

Can I copy those to another server to free up space or will that affect exchange in some way?

Thank you so much!

Why don't you just do a backup?  So, the tape drive is down.  Big deal.  The Windows Backup Utility can backup to a file.  Back it up to a hard disk or something.

Isn't never overlook the obvious the number one rule?  That's the one I always forget!

Thank you!  Quick question though, if I choose just the information store, will that flush the logs?

I need to do something about the log files, the Exchange server is running out of space.

Thanks!

Yes, that SHOULD be all you need to do, backup the information store using the Windows Backup.

Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

Do one thing. Dismount all the stores. By dismounting the stores, you make it "clean shutdown". A clean shut down database does not require the log files. Just copy it accross another drive over the network. You never know when you might need them in a disaster recovery scenario.

Yes as per the post above by Leew you can do a normal backup ( NTBACKUP ) and it will flush the log files.

Just additional info about different types of back up's

When backing up Exchange Server databases, there are four backup types available:

• Normal (or Full)   The normal backup process backs up the directory or Exchange store in its entirety, as well as the log files. To restore from a normal backup, only one normal backup is needed. A normal backup marks the objects it has backed up so that incremental and differential backups have context. This is accomplished by backing up the entire database and all the log files, and then purging the log files.
 
• Copy   The copy backup is the same as a normal backup except no marking takes place to give incremental and differential context. This means that performing an incremental backup after a copy backup is equivalent to performing it before a copy backup. Use a copy backup to get a full backup of the directory or Exchange store without disturbing the state of ongoing incremental or differential backups.
 
• Incremental   An incremental backup backs up the subset of the component that has changed since the last normal or incremental backup. Then it marks these objects as backed up. To restore from incremental backups, each incremental backup since the last normal backup and the normal backup are needed. An incremental backup backs up only the log files, and then purges them.
 
• Differential   A differential backup backs up changes in the directory or Exchange store that have occurred since the last normal backup. To restore from differential backups, one differential backup and one normal backup is required. A differential backup backs up only the log files but does not purge them.

  Note
In few cases, performing a differential or incremental backup is disabled, for example, immediately after an offline defragmentation or while circular logging is enabled.
 

To restore an online backup in Exchange 2000 Server, you need the Microsoft Exchange Information Store service running, and the stores that are being restored need to be dismounted. To restore an online backup in Exchange Server 5.5, you need to have the Microsoft Exchange System Attendant service running.

A clean shut down database requires no log files to get mounted again. As soon as it mounts it starts fresh log files. So the old log files is ready to be deleted.

Thank you all for your help, but I jsut realized I can do a backup to disk through Backup Exec which will resolve this issue, until the new drive comes in.

Thank you again!!!
