Can you check the cache location for how much free space is available?

Cause

The behavior in question may occur when the Enterprise Vault Server Cache location is either full or low on drive space.

Check the Maximum Cache Size within the VAC, see screen shot below:

Then check the size of the Cache folder to see if it is near the limit.

Export archive to PST files fails with events 6794, 6609, and 6769

Hello Tony , I had already went through above article.....

We have 390 gb space available on Cache drive out of 1 TB.....

And Cache  folder is also not using single MB

can you get a Dtrace of ExportArchiveWizard and MigratorServer during the export process

I have tried restarting the admin service as well.

Log has been exported what you want me to check on that, on Event viewer we have event ID 6769

Could be a problem with a specific item.

Do you see a crash event 1000 in Application Log ?

What is the behavior if you perform an export specifying a data range ?

You can also try to customize webapp.ini to include
RestoreTOPSTOption = All option and try a restore to pst from search.asp - Refer TECH54559

If you still have issues, need dtrace logs.

It seems it is failing on this: Failed reading S:\Enterprise Vault Stores\sonusevs1store Ptn1\2006\03\27\11\489715000000000~200603271125320000~0.ARCHDVS

Can you see if that file is actually there and if it is you can try deleting it and running the process again.

Typically archdvs files are cleaned up by the Collector task when they are older than 24 hours but it may not have happened it in this instance.

Hi Vishal,

What is the behavior if you perform an export specifying a data range ?

Yes when I am exporting after 2006 no issue

I had tested few more users & its going all good as of now...   Surely Tony I will follow your steps sometime later as right now all going good for other users.
