daylight savings time and NTFS

S

Steve Maser

Hi all!

With Daylight Savings Time coming up -- any HD formatted as NTFS
will change the time stamp on every file on the computer.

This, of course, affects my backups of my NTFS-formatted Windows
boxes.

Does anybody know if there's a way to have the time change at DST,
but *not* affect the time-stamp on NTFS formatted drives?

There is only one time (UTC), and this is what is stored in the time
slots in packets and file headers. How your computer or your clocks
display that time is your choice. Switching to daylight savings time
does not change the time but for many people, requires changing their
clocks.

There's different behavior between FAT32 and NTFS-formatted drives.

NTFS drives maintain the time stamp on the file based on UTC. FAT32
doesn't.

Our backup program (Retrospect) matches "changed" files based on a
number of criteria -- among which which is the "time created" and
another the "time modified" flag for the file.

When DST changes in April and October, all the files on NTFS formatted
drives get backed up all over again because their "time" has changed
since the last backup.

We're looking to avoid that and are open to suggestions.

Don't use retrospect. It's faulty.


That's neither here nor there to this question.

(I will say in Retrospect's defense -- I've been using it for 10+ years
and have been very satisfied with it. Sure, it's not perfect in terms
of features, but it has never failed to backup/restore data for me
whenever I've needed it.)

That's like saying, "My horse never died before."
