This is a SQL Script that I use on my test system to dump out all of my EV SQL databases to a BAK file and truncate the transaction logs. The only thing that needs to be changed is the location where you would like the BAK files to be created.:-
-- automated Dump procedure
-- dumps all databases in .bak files
use EnterpriseVaultDirectory
GO
Declare @BackupDir varchar(255)
-- CHANGE THIS IF NECESSARY
Set @BackupDir='D:\BACKUPEV\'
-- Use a Cursor to loop thru the Directory
-- in order to find all DB's
DECLARE dbcursor CURSOR FOR
select DatabaseName
from dbo.VaultStoreEntry
OPEN dbcursor
declare @dbname varchar(255)
declare @s varchar(255)
-- Perform the first fetch.
FETCH NEXT FROM dbcursor into @dbname
-- Check @@FETCH_STATUS to see if there are any more rows to fetch.
WHILE @@FETCH_STATUS = 0
BEGIN
print ''
print 'Backing up : ' + isnull(@dbname,'noname')
-- create a Backup device called 'temp' with type of disk
-- and Filename DBNAME.bak
set @s = @BackupDir + isnull(@dbname,'noname') + '.bak'
EXEC sp_addumpdevice 'disk', 'xtemp', @s
-- Truncate the logfile
print ''
print 'Truncating log'
BACKUP LOG @dbname WITH TRUNCATE_ONLY
print 'Truncated log'
print ''
-- Dump the DB into that file
BACKUP DATABASE @dbname
TO xtemp
WITH DESCRIPTION = 'Enterprise Vault Backup', INIT
Usual legal disclaimer stuff that if you are going to try this script on a production system then please get it verified and tested on a suitable testing platform. ETC ETC :)
