Just one more important note. If you are using rsync over the wire (as
opposed to synching local folders), gzip with "rsyncable" is preferable
to bzip, as it does not obliterate rsync's wire efficiency.

Re: Compressed destination files

Thanks for the info. FYI I tried the patch and it appears to have worked. 
I'll keep the list updated if I find any errors...


A couple ideas. Rather than only using the time stamps to determine if 
files need updating the file size could also be used by 1) putting the 
filesize into the new filename (ie test.1231098.doc) or 2) creating a 
separate file with a list of the file sizes for all the files.


Also, it might be nice if rsync added the bz2 extension to the output 
filenames so it was obvious the files are compressed and make it slightly 
easier to decompress (ie without renaming).


Not major concerns, it should work fine with just the time stamps, and 
having to rename isn't a big deal. Just ideas. Thanks to all who work on 
rsync.

 I would like to do an incremental backup using rsync where all the files
 at the destination end are compressed (bz2).


Currently, the only way to make rsync do this is with the experimental
patch "source-filter_dest-filter.diff", which is distributed in
"patches/" in the rsync source package.  If you compile a custom
version of rsync containing this patch, you can specify bzip2 as the
source or destination filter.  Read the top of the patch for more
information.  The patch is only a first attempt, so you might not want
to trust it with your backups yet.

Compressed destination files

2006-11-29 Thread Joshua Grauman

Hello,

I searched the list and found some similar questions, but no answer, so...

I would like to do an incremental backup using rsync where all the files 
at the destination end are compressed (bz2). I'm backing up to a usb flash 
drive and would like to fit as much as possible on it. I would also like 
to avoid rsync'ing to another directory on my hard drive, and then 
bzip'ing that. Done this way only the modified files will need to be 
copied/bzipped, and if I want to restore a single file it is easy. Any 
ideas? Thanks.
