Time Machine In Your Pocket – Addendum
Addendum to two previoius posts.
The other day, I noticed my 8GB USB volume that I use for temporary incremental backups was quite full. Curious, since the folders I back up to that volume do not total but 200MB or so, and rsync was supposed to be doing incremental backups (link-dest ftw).
After a little searching around, I found someone who had a similar problem (and a solution). When you format a volume with OS X it will, by default, ignore file ownership (the linked article explores why this is perhaps). This proves to be a problem for rsync which considers file permissions and ownership as part of the file stat (as it should). Luckily the fix is easy – “Get Info” for the volume in question, then at the bottom unselect “Ignore ownership on this volume”
You will probably want to delete any backups that have been created (since they won’t have the correct file ownership). Source: Terminalapp.net
Don’t forget to encrypt your whole USB volume first in case you lose it!
