comment How long does it usually take to format a 2TB external HD using ext4 and gparted?
ext4 can be formatted in a defered way, where most of formatting commences in background while the filesystem can already be used after a very short initalization period. Using mkfs.ext4, the option would be -E lazy_itable_init=1, and this even is a default setting it seems. I don't know how to make gparted using this option, but maybe it is possible. Using this feature, a 2GB partition gets available after about one minute.

Sounds good! As I am not using rdiff-backup in daily procedure now, may I ask if you tried this successfully?

comment Is it possible to make the OOM killer intervent earlier?
I think this answer is a bit like 'don't do anything real bad to solve a problem' but in my opinion a system that can made unresponsive by a bunch of seemingly harmless user actions is worse than a system that kills them early.

comment How to store file attributes like permissions and timestamps and reapply them later on linux?
Yes, but I want to store the attributes alone. I use other tools to store the files, but they do not reliable store attributes. So I like to use something that is able to store attributes but don't neccessary the file contents.

That seems to be a dead end. rsync works well if the trees are identical except the timestamps, but if there are any other changes, it gets too complicated to keep rsync from applying them either.

This works well, except it is a little slow as you stated. Suprisingly, it does makes several hundred files per second, which is quite cool if you remember a new touch is run for every file.. however, I will try a Python script like you propose.

Even when using --existing, there is still some risk loosing modifications made to some files since the duplication. Maybe there is some way preventing rsync from copying content at all? Then the problem would shrink to some resetted timestamps. On the other hand, using rsync without --size-only would give a precise picture of what files would need a new timestamp and which do not. Using with -n for dry run, I would get a list stating >f for files that would be reseted but should not, and .f.t for files that are old and would get the correct old timestamp. But how to apply it then?
