Is using Backup Exec CPS with an external drive recommended?

Posted on 2007-07-25

Considering purchasing Backup Exec Continuous Protection Server.  How would this differ (in terms of recommended Backup destinations, not features) to the backup-to-disk feature of Backup Exec?  Would an external hard drive work well for CPS?  Are there any special recommendations for Exchange?

    backing up to external drives via backup to disk is Ok in my opinion, but for higher end work I would suggest not going this route.  the only reason is that when you're protecting hard drives which are prone to failure by backing them up to... another hard drive.  the convenience of tape to date has been the relative inexpensive cost per gigabyte of storage and the fact that the cartridges are palm sized.

    granted they make smaller and cheaper external hard drives these days, i really just wouldnt trust an external tape myself.  For a small office, there's nothing wrong with this.  Make sure to take the drive off site every night to make sure that fire wont wipe out the backups too.  (yet another reason tapes were so effective which is portability)

    If you're going to back up to disk though, I really would just configure some storage elsewhere on the network to accept backup exec's dump files and back them up accross the network to a raid protected array of storage.  at least it will be in another location physically (given the WHOLE building doesnt burn down anyway)

    I have used Backup Exec to external drives in the past without the CPS addon, and am aware of the limitations in that situation.  My question was more geared towards the differences of having a backup window to disk and having a continuous protection server to disk.

    You can only use hard drives with CPS
    CPS does not support backups to TAPE
    You can continuously protect the transaction logs with CPS
    and Full backups of Exchange with BE

    Forgot to add CPS  comes for FREE with Backup Exec
    if you did not get it you can download it from
    you will need the SERIAL NUMBER associated with yr product (not the license)
    you can find it in the product documentation
    eg      M1234567890
    it will most likely start with a M

    also CPS is free
    but any computer you want to protect with CPS will need a license called AWS or Agent for Windows Server which is a paid option.
    CPS cannot protect the server its installed on
    Its a replication software and Source and Destination cannot be the same
