10.5: One way to use Time Machine and a backup server
Authored by: knappis07 on Jan 23, '08 08:54:49AM

Great hint. I'm looking for the same functionality but I have trouble making it work.

I have tried a modified version of your hint to mirror my TM backup volume to an external drive.

I used the following code:

sudo rsync -a -H -E -v --progress --force --delete-after /Volumes/TM/ /Volumes/BKP_TM >> ~/Library/Logs/rsyncTM.log

The full TM volume was ≈50GB including about 15 backups and there seem to be something wrong with rsync intepretting the hard links since the file count went extremely high and it finally exited with an error (se below).

Does anyone have a clue whats wrong?

To OP, is it still working for you and have you made any modifications since your first post?

building file list ...

......

37143100 files...

rsync(1107) malloc: *** mmap(size=262144) failed (error code=12)

*** error: can't allocate region

*** set a breakpoint in malloc_error_break to debug

rsync error: error allocating core memory buffers (code 22) at / SourceCache/rsync/rsync-30/rsync/util.c(120)

I know it seems like a small thing, but can you try your command and change "/Volumes/TM/" to read "/Volumes/TM/." (make sure that trailing period is there)? Let me know if that makes a difference.
