    Default Difference between 'versions data exists' and 'versions data deleted'

    Hello,

    Here is the definition of our copygroup:

    tsm: TSM1>q copyg SHARE-PD ACTIVE PROJECT-MC

    Policy Policy Mgmt Copy Versions Versions Retain Retain
    Domain Set Name Class Group Data Data Extra Only
    Name Name Name Exists Deleted Versions Version
    --------- --------- --------- --------- -------- -------- -------- -------
    SHARE-PD ACTIVE PROJECT-- STANDARD 3 2 45 No Lim-
    MC it

    Here is my understanding of versions data exists and deleted :

    1) So if a file is deleted by the user or "expired" by the admin, it
    counts as "versions data deleted", which we keep 2.

    2) The last backed up file counts as "versions data exists", and it is active.

    3) If a file is modified, it counts as "version data exists", and will be inactive. We keep up to two inactive versions, and 1 active versions.

    Am I correct, or I misanderstood something?

    Thanks,

    Andras

    Hi,

    yes, you are correct - but keep it simple - if there is an active version (so the file existed on the filesystem during the last backup) then VEREXISTS parameter is used. If there is no active version (file was deleted and the backup was run OR administrator expired the file) then VERDELETED applies.
