    DUMP TRANSACTION is the ASE command for an
    incremental back-up.

    Keep in mind that ASE only allows DUMP TRANSACTION
    when the logsegment has its own device and when no
    minimally logged activity occured. Usually, the DBA
    prevents minimally logged activity on a database by
    setting the option "select into/bulkcopy/pllsort" to false.

    What DUMP TRANSACTION does is to save the log
    contents to file (or tape). Since the log records all
    SQL activity, ASE can use it to redo it should the database
    be restored. Restore is performed by executing LOAD
    DATABASE from a file or tape created by DUMP DATABASE,
    then loading all log dump files by several LOAD TRANSACTION

    Some options of the DUMP TRANSACTION like WITH NOLOG
    or WITH TRUNCATE_ONLY do truncate the log instead of
    saving it. No new DUMP TRANSACTION to file is possible after
    one of those, and recoverability will require to perform a
