Unzip of a whole directory might be very easily overlooked - unzip will
restore both attributes (without "archive" bit) and file date. Thus
selection based on this criteria will fail. OTOH ADSM/TSM will see a file
without a corresponding entry in server DB. Such a file enters in the list
of files for backup.
The situation may also be triggered if you lost for some reason a tape.
"del vol <tape> disc=y" will clear entries in DB and on next backup files
will be sent to the server (if cannot be restored from copypool).

        Subject:        Journal Based Backup and Legato Networker


Hi *SM-ers,

could one of the knowing (ex)-Networker users help me in interpreting the
following sentence
in the "Legato NetWorker, Release 6.2, Microsoft Windows Version
Administrator's Guide",
page 593:

"When using the Change Journal, the NetWorker software can detect more
types of changes and can save more changed files than is possible when not
using the Change Journal."

Networker uses the MS Windows 2000/XP builtin Journal.
So does this mean that a "normal" incremental backup doesn't get all
changes?
As I understand Networker uses the archive flag and the last modified
date.

What kind of changes could go unidentified?

Is my understanding correct that TSM always gets all changes (incremental
or
journal based
backup)?

Kind regards
