Hi,
I'm probably not the only one who noticed: after deactivating and reactivating
a large port like Qt5, the next Time Machine backup announces (or at least
claims) to have much more to backup that one would expect (over 1.5Gb in case
for Qt5). That suggests that the backup engine looks at more than just file
name, size and date alone; possibly taking the inode number or equivalent into
account too.
Is there a good way to exclude most of MacPorts from being backed up while
retaining the possibility to reinstall without rebuilding? I'm thinking of
backing up selected bits from var/macports (notably the registry and software
directory), probably etc/macports and libexec/macports. There's however the
issue of user config files; are there designated locations to install such
files?
I have already excluded var/macports/{build,log}.
Superfluous backing up of course ends up wasting significant amount of space on
the backup disk esp. for developers who regularly to something like `port -n
upgrade --force` after an incremental rebuild with only minimal changes. It is
also costly in terms of time when you're using a NAS like my Time Capsule (even
when connected via a wired gigabit connection).
Thanks,
René
