> I have an automated script that backups my database, ftp's it to a test

> This process works 95 % of the time.

> Occasionally the restore of the database fails as it asks for an archive

> My backup is something like this:

> 1) ALTER SYSTEM ARCHIVE LOG CURRENT
> 2) Start Begin and End Backups and copies of all tablespaces.
> 3) ALTER SYSTEM ARCHIVE LOG CURRENT
> 4) CopyArchivedRedoLogs (From the time of step1 to tep 4)

> So my question is do you ever require the archive logs that are generated

> If you believe what I am suggesting is impossible please let me known and
