Hi,
I know those
questions have been asked before
but that was more
than an year ago.
I'm hoping the
situation has evolved now.
I'd like to use
rsync as a backup tool
to move around some
data.
I often have to move
hundreds of GB,
and that takes some
time. I'd like to use rsync
so that if something
happens, I can restart
the migration
without loosing what has already been transfered.
But I noticed that
every time I use rsync to backup
some data, it
"corrupts"/updates the access time of the source file.
All the backup tools
I've previously used preserve the access time
(otherwise, you'll
loose your access time if you backup everyday).
Gnu tar has a
"--atime-preserve".
I use both the
access time (last read) & modification time (last write)
to identify which
files to remove from the fast file server.
(I've written a tiny
perl script to identify which files are "old").
I wish there was an
rsync option to preserve access times (sce & dst).
I would also be
delighted if there was another option that would
allow to
compress/gzip/bzip files on the destination.
I believe that by
having almost same filename -> filename.gz,
and having all times
(A, C, M) identical, would be sufficient for a match ?
Why compressing
files ? it's the best trade-off between ease of use
and compression.
having no compression at all for old files leads to
waste of space (even
on a cheap slow file server).
Compressing
everyfile into a big tarfile makes it difficult to browse
a huge archive (I
don't know of a "tar shell").
Keeping the
directories uncompressed allows for browsing the data
easily.
please
?
Thanks in
advance,
