.pst Backup and Restore

Hi,

I was unclear on the following point.

 

From DLO7 Datasheet

Microsoft Outlook® mail files (PST) protection: Protects PST files at the message level.

 

Using VSS Symantec DLO7 has an added feature to backup open .pst files too?

also can it restore individual emails and without restoring the complete .pst file?

 

Can Some one who has tried this out please explain

 

Thanks,

Anurag

    Here's some excerpts from the DLO7 Admin Guide you may find useful :

     

    ---------------------------------------------------------------------------------------------
     
    The Desktop Agent is designed to protect open PST files if they are
    part of the profile or user's backup selections. Incremental backups must be enabled for open file backups of PST files.

    ---------------------------------------------------------------------------------------------

     

    Backing up Outlook PST Files Incrementally
    DLO is configured to back up PST files incrementally by default. Incremental backup of PST files is
    controlled by the administrator in the Profile, or by the desktop user in Options dialog if the desktop user
    has been granted sufficient rights.

    Note: Outlook must be the default mail application to perform incremental backups of Outlook PST files.

    The following limitations should be considered when backing up Outlook PST files incrementally:
    ■ Some of the DLO options are not used, even if they are enabled. These options include Delta File
    Transfer, Compression, and Encryption.
    DLO relies on Microsoft's Messaging Application Programming Interface (MAPI) code to perform the
    actual backup of PST files. Using MAPI does not allow the use of these DLO options during an
    incremental backup.
    This is a limitation of the way the incremental backups are performed and is normal behavior for
    backups of Outlook *.pst files . This limitation only applies to incremental backups and does not
    apply to non-incremental PST backups.
    ■ When Outlook PST files are backed up incrementally, only one revision is maintained regardless of the
    number of revisions set in the backup selection.
    ■ When you restore Microsoft Outlook PST files, the restored PST file will differ from the original PST file
    as explained in Restoring Microsoft Outlook Personal Folder Files on page 230.
    ■ Synchronized files cannot be backed up incrementally.
    ■ When a DLO profile is configured to limit the bandwidth usage during data transfer to the network user
    data folder, bandwidth is not limited during the incremental transfer of PST files.

    ---------------------------------------------------------------------------------------------

     

    Restoring Microsoft Outlook Personal Folder Files
    When you restore Microsoft Outlook Personal Folder (PST) files, the following differences will exist
    between the restored PST and the original PST:
    ■ The file size will be different
    ■ Any rule that points to a folder inside a PST file will no longer work. You must edit the rule to point to
    the correct folder
    ■ Restored PST files will have Inbox, Outbox, and Sent Items folders, even if the original files did not have
    them
    ■ If you use a password for your PST file, you must reset the password after restoring your PST file

    Hi,

    Thanks for your reply that does clear out many things.

    So does it mean that singular emails cant be restored? Complete .pst will have to restored on any system and then only the particular mail can be retrieved?

     

    Thanks
