Backup execution problem


Recommended Posts

Hello,

 

We are currently running Retrospect version 5.0.238 on our OSX server.

 

There are two users of this server, both of which log out of their workstations at the end of the day.

 

Each night we run a scheduled full backup to tape. This backup begins at 7pm. However, when the two members of staff start their shift at 6:30am the backup is still running. I have to manually stop the backup. As a result the only successful backup we get is on a friday. The friday backup begins at 7pm and completes at 5:30am on the following sunday!

 

We have looked into the scheduling of the backup jobs and cannot find anything wrong.

 

However, we have found a solution albeit impracticle. At the end of the day if we reboot the server the backup executes at 7pm as scheduled and finishes before 6am the following day.

 

Any advice / ideas you guys have would be greatly appreciated. Why would rebooting the server allow us to do a successful backup within 12 hours? I need a solution to this as I cannot keep rebooting the server every night.

 

If you need me to post any further information then please reply and I will supply whatever is needed.

 

Thanks in advance guys.

Hello,

 

This is a copy of the Log from last night. I rebboted the server before I went home and the backup started at 6pm and successfully completed at 6:30am. I will post the log from ther day before in a seperate reply. The day before I had to stop the backup as it was taking too long.

 

Hopefully this log will reveal the problem...

This is a copy of the log where the backup took too long and ran into the next day. Unlike the log above, no server reboot was performed before backup execution.

You should clean your tape drive. It has been used for 17 hours since the previous cleaning reminder.

In both cases, the first Execution of your script, "Mirror1," completes 1.5 GB of data in about 16 minutes:

 

Completed: 53307 files, 1.5 GB

Performance: 193.1 MB/minute (161.9 copy, 239.3 compare)

Duration: 00:16:55 (00:01:43 idle/loading/preparing)

 

The second Execution of your script, "Mirror2" completes the first night, but at substantually slower speeds:

 

Completed: 19338 files, 70.9 GB

Performance: 34.5 MB/minute (38.1 copy, 31.4 compare)

Duration: 02:36:20 (00:01:46 idle/loading/preparing)

 

And this same volume takes 14 hours to get finish only about three quarters of the data.

 

So the question becomes, what sort of drive is "Mirror2?"

There is something odd going on with this backup, the numbers do not match up. With that performance it should have taken over 24 hours to back up 70 GB.

 

The later backup that ran out of time shows a duration that matches the performance, and the total backup does not fit into 12 hours.

 

I suggest taking a look at which files have been backed up using Reports > Contents.

 

(Wild speculation, perhaps a very large and inappropriate file, like a virtual memory or cache backing file, is included in the backup. It might consist mostly of zeroes when the computer is first booted. I don't whether this explains the odd performance figures though!)
