UNSET, UNSET_ALL directives, and multiple data streams

All policy-specific directives that are passed to a client in a stream are passed in all subsequent streams. The UNSET and UNSET_ALL directives change this behavior. These directives are recognized only if the Allow multiple data streams option is set for the policy.

UNSET

The UNSET directive interrupts a policy-specific directive so it is not passed with any additional streams. The directive that was unset can be defined again later in the backup selections list to be included in the current and the later streams.

In the following backup selections list, the set command is a client-specific directive that is passed to the first and all subsequent streams.

NEW_STREAM
set destpath=/etc/home
/tmp
/use
NEW_STREAM
/export
NEW_STREAM
/var

For the set command to be passed to the first two streams only, use UNSET or UNSET_ALL at the beginning of the third stream. At this location, it prevents SET from being passed to the last stream.

NEW_STREAM
set destpath=/etc/home
/tmp
/use
NEW_STREAM
/export
NEW_STREAM
UNSET_ALL [or UNSET set destpath=/etc/home]
/var

UNSET_ALL

UNSET_ALL has the same effect as UNSET but unsets all policy-specific directives in the backup selections list that have been defined up to this point.
