System: OS X Snow Leopard (10.6.8)
Symptom: Backing up minor changes (few MB) would take a really long time, and the rate of backup would be on the order of KB/s. The system tries to prepare hundreds of thousands of files. The Time Machine drive had a fresh full backup.
/.fseventsdon your startup drive or move it to another location:
mv /.fseventsd /.fseventsd.bak
- Start a Time Machine backup
Speculation: When Time Machine can’t find
/.fseventsd, I’m guessing it does a deep traversal (according to my system.log), which I take to mean scanning for changed files, and then rebuilding the metadata for
/.fseventsd. More discussion at https://discussions.apple.com/message/18923411?ac_cid=tw123456.
