  • Closed as program error.

Error description

  • For snapshot differential (snapdiff) backup operations, the
    backup-archive client creates and maintains a local "change log
    database" to track filer volume changes. If the client detects
    that the change log database was not closed correctly by a
    previous snapdiff backup operation, the backup operation stops
    with return code 12 and a scheduled backup operation is reported
     as "failed".
    
    The following messages are written to dsmerror.log:

Local fix

  • The problem can be temporary fixed until the correct code is
    applied running the SnapDiff backup using the CreateNewBase=Yes
    option:
    dsmc incremental -snapdiff -createnewbase=yes
    <path_to_the_volume>
