Well, this seems to do what I want, as near as possible - enable or disable
Time Machine depending on whether the backup drive is mounted, and in either
case (since this doesn't seem to be remembered!) turn off local snapshots,
which seem to me not a great idea with an SSD, at least if one doesn't need
such a guarantee that backups will be particularly recent.
using terms from application "Growl"
on evaluate notification with notification
if notification's app name equals "HardwareGrowler" then
if notification's note title equals "LaCie Mounted" then
do shell script "sudo tmutil enable;sudo tmutil disablelocal"
else if notification's note title equals "LaCie Unmounted" then
do shell script "sudo tmutil disable;sudo tmutil disablelocal"
end if
end if
-- absent an explicit return, defaults are used
end evaluate notification
end using terms from
This does assume that the account using it is able to do a "sudo" without
password; other than that and the name of the volume mounted or unmounted, it's
probably fairly generic for such a use. Having the Script Editor show me
Growl's dictionary, along with looking at actual recent examples in the Growl
log, provided the information I needed.
AppleScript was clearly descended from something intended to appeal to
non-programmers; as such, it makes my head hurt a bit; but for something small
that can't as easily be done any other way, I guess I can live with that. :-)
