Like I said in my posting above, TT doesn’t pass good arguments to hdiutil. Since you seem unable to compare the differences, I’ll do it for you.
This is the command TT uses:
$cmd = “hdiutil create -size $size\g -fs HFS+J -volname “TM-backup-of-$host” $SBfilename”;
This is the command CBV uses:
CMD="hdiutil create -nospotlight -imagekey sparse-band-size=131072 -size $VOL -fs “Case-sensitive Journaled HFS+” -volname “Backup of $HST” ~/Desktop/$
Specifically, the following arguments are important:
-nospotlight -imagekey sparse-band-size=131072
(sadly, apple seems to ignore the -nospotlight, but might as well put it in there)
the sparse-band-size is VERY important because otherwise the default tiny size is used and since TM writes a lot of data to sparsebundles (generally over the network), then opening a ton of tiny files is a major speed slowdown.
This is a very simple fix for TT, but nobody is making the effort to do it. Until it is done, it should be removed from the DR website.
The other problem with TT is that it kind of implies that backing up over SMB is ok. That is the furthest thing from the truth. Read the BMFU mailing list for more discussion on the matter.
