Need an explanation of what the local EV db's are?

[ap1111]

I'd like an explanation of what the local EV db's are located here on c:\ drive,  ....\local settings\app data\kvs\enterprise vault\ecdf453dcfg....\    

There are very large db's, in addition to xml and ini file.

Do these db's need to be here, can they be deleted?  If yes, will there be any issues?

thanks.

You are in the wrong forum, I will move this over to the Enterprise Vault forum for you.

These DB files are used for Offline Vault (if you are using Enterprise Vault 2007 clients or below) or Vault Cache (if using Enterprise Vault 8+ Server and clients)..... The db files are basically PST files that contain local copies of the messages contained in the users archive.

If you are using Enterprise Vault 8 and Vault Cache then the DB files are created on the server first and then downloaded to the client which is then placed in their user profile on the machine, once downloaded the DB files are then deleted from the server

If you are using Enterprise Vault 2007 and Offline Vault then the DB files are only created on the users machine and download.asp downloads each individual message to the DB files.

If you just go ahead and delete the files straight off then what will happen is that the next time outlook opens it will simply start rebuilding them again, and users will be affected if they expect to be able to open items offline and now start getting errors.

This is all controlled by the policy, in Enterprise Vault 8 it will be in the Desktop Policy for the users, in Enterprise Vault 2007 it will be in the mailbox archiving policy under the Advanced tab in the Desktop drop down menu

Understand, but why are there so many different db's in that folder?  There are approx. 25 db's with different dates and sizes ranging from 100mb - 417mb, sometimes the db size is the same but the dates are different.

Thankyou.

The date range is based on the Sent/Received date of the emails.
Because of the "fragility" of large PST files, its easier and more performant to have a dozen PST files at 250mb than one GIANT PST file at like 20GB that could become corrupt.
