Changing to an SSD RAID system forced me to rethink what I needed to back up and when, rather than just leaving to Time Machine.

Now collects log entries reporting progress and rates of transfer during a backup, and giving info on what is slowing them down.
How can you tell what causing a backup to run so slowly? If it is this bug, what can you do about it? A plain user’s guide.
Surely these problems with Time Machine are old hat and not news? Or are they simply errors occurring with disks or the file system?
Document versions can be invaluable, being between Undo and your backups. But they’re also easy to lose. Here’s how to keep them.
Time Machine seems to be the only backup system which also backs up the Versioning database on each volume. Is that useful though?
When making a first full backup of less than 2 GB takes 86 minutes, and you then can’t restore from it anyway.
The plan was simple: replace my 8 year-old Promise Pegasus RAID system with a shiny new SSD RAID system, for Time Machine backups. What could go wrong?
Here’s what happens when a Time Machine backup, normally the first, slows to the point where it’s just never going to finish.
If a Time Machine snapshot can’t be thinned, nothing warns you of the problem, and without Terminal or the log you can’t even find out.
