Comment #9 on issue 25959 by [email protected]: Chrome history &
thumbnails fill up timemachine
http://code.google.com/p/chromium/issues/detail?id=25959
Excluding an item from a TM backup is simplicity:
bool success = CSBackupSetItemExcluded((CFURLRef)url, true, true) ==
noErr;
Unfortunately, we must not just exclude the main database but also the
associated '-journal' and any associated
'Index nnnn-nn' and their journal's, too. Excluding the main database file
is easy: just exclude it immediately after
opening. The -journals are created by SQLite each time an outermost
transaction is begun, which is somewhat
more complex. And the Index files are created by SQLite when a view is
indexed, which is even more 'interesting'.
Fortunately, the -journal and Index files are always created in the same
directory as the main database.
The best approach, IMO, would be to put the History and Thumbnail database
files into a 'History' sub-directory
and then mark the directory to be excluded from Time Machine. This would,
unfortunately, require a migration.
