Hi there, penguins!
As a deletion of /home is not necessary at all when moving to an upgraded System (hint), I´d like to know hwo it might be possible to super-squeeze /home.
Of course, using an external drive would be the easiest way to go, but what to do if /home is HUGE and no adequate HDD is around?
Which command does exist to super-compress home as much as possible in oder to uncompress it on the new system?
NOTE: I am not looking forward to compress /home with any archiving tools like Arc.
I believe Ark (like file-roller) is just a frontend for the apps on the
backend. If you have a huge directory to squeeze, though, the same
technologies apply. To move them quickly with low compression just use
tar but to actually squeeze (rather than just bundle) data into a smaller
space use a compression application like gzip or bzip2:
tar -cvf /tmp/yourUserHomeDirectory.tar /home/yourUser #bundle
tar -zcvf /tmp/yourUserHomeDirectory.tgz /home/yourUser #gzip compress
tar -jcvf /tmp/yourUserHomeDirectory.tgz /home/yourUser #bzip2 compress
Once done move the /tmp/whatever file to your new box.
Good luck.

Umpf, isn´t there some other way to do this? When doing this like you suggested, I´d have to install Ark again - and I´ve uninstalled it for a reason.
Which internal compressing commands do exist for OpenSuse?
If it’s about moving /home to a new system, I never compress. I put the new drive in my main system, ‘dd’ /home to the new disk, after that enlarge the partition if needed.
‘dd’ is a command to copy data byte-by-byte from one place to another.
Personally I do not know why you would use this over just a plain old ‘cp’
of data from the source to the destination (especially since you could
have the destination be a larger size from the start) but hopefully that
explanation will come. Using ‘cp’ and other commands also means you can
optimize transfer of things like sparse files.
Good luck.

Had /home on a 120GB, bought a 250GB, put it in the machine, did:
dd if=/dev/sd[homedisk] of=/dev/sd[newdisk]
Used partitioner to enlarge /home partition on the newdisk, and mount it instead of the old one, done.
Is that what you meant? A ‘man dd’ will give you all the info you need.
missed some things. Indeed cp -r -p would do the job as well. It’s an old habit to use ‘dd’, it never failed on me. As it is an old habit to have /home on a separate disk.
Nope. I intendet to compress it as much as possible with soe tool/command that does not take me 500 years to do the job and uncompress it later after upgrading.
