    Unanswered: Backup open Pervasive DB

    Hello,


    is it possible to backup the "data-files" of an open/used Pervasive SQL V8.6
    (standard version) with a backup-software or is the Pervasive Backup
    Agent required ?


    Thank's a lot for any tip,

    John

    The backup softare will need to put the open data files into "Continuous Operations" mode. Sometimes this is done with an agent and other times, you may need to use a batch file with BUTIL -STARTBU.

    Thank`s Mirtheil for the helpful informations.

    How can we find out if we should use "BUTIL -STARTBU"
    or the Backup Agent?

    What happens if the user tries to "update/add records to the DB"
    during backup of the database (e.g. with a backupsoftware).

    Are the changes made during backup simply lost or do you get a
    message?


    Thank's for any clarification,

    John

    Backup Agent is just a wrapper around the functionality that BUTIL -STARTBU uses. THey both do the same basic thing, just in different presentations.

    If the open files are in "Contnuous Operations" mode (by STARTBU or BA), Delta files are created and any changes are logged to the Delta files. Once Continuous Ops is turned off, those changes are merged into the main file.
    You really should take a look at the docs on COntinuous Operations. Here's a good start: http://www.pervasive.com/library/doc...vops-09-5.html
