Hi Roger,
Tks for your advice.
If you want to synchronize (i.e.
update
to the latest version, no matter where it is), try unison.
Whether you suggested;

I'm trying to find out whether real time synchronization is possible,

In the rsync man page.
rsync -ax ~/ /mnt/extdisk/myhome/
should do it.

Hi Neil,
In the rsync man page.
rsync -ax ~/ /mnt/extdisk/myhome/
should do it.
On which file of cron shall I add following line to rsync
/mnt/extdisk/myhome/ quarterly?
0,15,30,45 * * * * rsync -ax ~/ /mnt/extdisk/myhome/
Whether -u update will do incremental copying for those files
Try to add --delete.

Yes. One of the more underestimated tools,

That's not what -u does, rsync does incremental copying by default, read
the man page.

Hi Bryan,
Tks for your advice.
Why not just use rsync?
setup cron to just sync the two directories (/home/blah with
/mnt/disk/blah) over and over?
Such an arrangement will only sync /home/user on

Hi Neil,
Do you really need such frequent syncing? Bear in mind the limited
write
lifespan of flash memory, if you have a file in your home directory
that
is frequently updated, you could wear out the memory in a short time.

Hi Etaoin,
Tks for your advice.
If you have networking, why not set up a network share of some kind
(nfs,
smb, or even ssh via shfs) and mount it (under the same path) from
each
computer you work on? This avoid having to replicate data and, with
decent network speed, is nearly as fast

why you need real-time mirroring. A script to sync the drive before
unmounting would give you an accurate mirror. A cron script to check
if
the drive is mounted and sync it every hour would cut down on the
amount
of data to sync when unmounting.

Hi Neil,
Shutdown involves unmounting the drive, and I recommended syncing
before unmounting.
The USB enclosure will be automatically mounted/umounted.
Whether on the script includes syncing once before poweroff/reboot
starts.
Where can I find similar syncing and cron script examples? TIA
