7.7.3 Transaction Logger
NOTE: Before using the Transaction Logger, you should refer . ,to the System Management and Support Guide .
. TheTransaction 'Logger records' disk file updates ~n :magnetfc tape as the updates .are made. In the event of a system fail- . ure, the tape can be'u~ed in conjunction with a File~Save
tape to restore all files to their state at the time of the failure.
A transaction is considered any,. one of the followinci: item update, item deletion, file creatior'l,- file deletion, and.'flle clearing for any disk file on the system. The Transaction
will experience problems when you attempt to,restore the data.

1. Activate the transaction logger immediately after a ,full File-Save (see "section 7. Sfor instructions),.-; ", '2. Do an ALL-UPDATE~SAVE'orPART-UPDATE-SAVE every day,(sE3e
'section 7. 7 for, instructions) . ' '
3. Do a full File-Save regularly, at least once a week (see section 7.2 for instructions).
4. Make sure each transaction tape is associated with the latest "save" tape (either Update-Save or File-Save). For example, if the latest "save" is a full File-Save, then the transaction tapes made after the save are associated with this File-Save "tape. But if an Update-Save
(ALL-" VPDATE-SAVE" ,or "PART-UPDATE-SAVE) ,was, done,' then" the'"
transaction ~,tapesmade 'after the Update.-Save are associated with the Update-Save tape.
