Sparse image compacting automatically
I got tired of checking the size of my sparse images and manually compacting them with hdiutil. So, I added the script fragment below to the end of the "daily backup applescript" which I had already modified for my specific volumes:
tell application "Finder"
activate
eject disk "Music Backups"
end tell
activate
display dialog "Awaiting dismount of Music Backups" buttons {"OK"} giving up after 5 default button 1
-- compact the sparse image to prevent unregulated growth
do shell script "hdiutil compact " & "\"/Volumes/Eds Office Backups/Music Backups.sparseimage\""
activate
display dialog "Music Backup Complete" buttons {"OK"} giving up after 30 default button 1
The "activate" verbs cause the script to become the top application so the dialogs show up (for testing, mostly); the dialogs are all for information and time out. I wait 5 seconds for the dismount to occur: always enough time unless the volume cannot be dismounted for some reason. hdiutil will not compact a mounted sparse image.
Hope you find this useful.
