>The server level 3.1.2.30 introduced an error in expiration processing =
such
>that the wrong policy attribute may be used to expire data.
> To encounter this situation, the following would need to occur:
>
>1) A given file would need to have multiple inactive versions of a =
file.
>2) The file has no active versions (the file was deleted from the =
client
>filesystem and an incremental backup was run).
>3) When expiration is run, all versions of the file are eligible to be
>expired under the "RETAIN EXTRA" policy attribute.
>
>In this error, the last version of a backup file may be managed by the
> RETAIN EXTRA policy attribute instead of the "RETAIN ONLY" policy
attribute.
>
>This can only occur if:
>
>- multiple inactive versions of the file exist when expiration is run.
>- all the inactive versions are eligible to be expired under the RETAIN
EXTRA
>when expiration is run.
>
>In this situation, the last backup version of the file can be deleted
incorrect
>using the "RETAIN EXTRA" policy attribute when it should have been
> managed by the "RETAIN ONLY" value.  The description above describes
>how this can occur.
>
>IF YOU HAVE ALREADY APPLIED 3.1.2.30 and you are exposed
>
>1) Halt the server
>2) Set the server option EXPINTERVAL 0 (in the server options file).
>3) Re-Start the server
>
>We are working to correct this as soon as possible
