[TynesideLUG] Copying data between two Ubuntu systems

[Alan Page]

 Hi Ian
When I routinely copy my home directory to an external drive I use
rsync -avz {source} {destination}
for a first copy, then for a subsequent syncing of files:
rsync --del -avzu {source} {destination}
which only updates files that are new or have changed, and deletes files from destination that no longer exist in the source. I have used this method for a long time, and not knowingly had any problems.

 Hi,

I've got 176G to copy between two Ubuntu systems, most likely using a USB 2
connected external hard drive formatted as ext4, possibly some time this
week.

Not sure if the UIDs and GIDs of the files from one system match the
equivalent ones on the destination system. So I might have to use the chown
command with the recursive option on the destination system.

So I was thinking of using Nautilus to copy data to the hard drive, step by
step, in more manageable stages than copying everything to the external
drive in one massive data transfer.

I think I've identified all the gotchas. What do you think?

TIA,


Ian
