Restarting Time Machine Backups after a Restore
Once you've restarted after restoring your data, Time Machine will
start over from scratch with a new, full backup—it essentially ignores
your previous backups. Apple claims this is “normal” behavior ,
though it may not be what you expect or want. (If you use Setup
Assistant or Migration Assistant to restore a Time Machine backup
to a new Mac, you can avoid this problem and continue with your
existing Time Machine disk by clicking Inherit Backup History when
prompted. See this troubleshooting page by James Pond for more .)
If it is what you want—you want to keep your new backups separate
from your old ones—then let Time Machine proceed on its own (or, if
using Setup Assistant or Migration Assistant, click Create New Backup
when prompted); to see your previous backups from before the
restoration, follow the procedure just previously in Restore Files from
Another Time Machine Backup .
If, however, you want your restored system to continue using your
existing Time Machine backups, you can use a special procedure to
reconnect them. To do this, follow the steps James Pond outlines .
Restore Files without Time Machine
If you ever need to restore files and Time Machine isn't working for
some reason, you can browse the contents of your Time Machine disk
in the Finder, and then drag any file to your Desktop (or another
folder) to copy it to your main disk. But be aware that Time Machine
stores files on your backup disk in two different ways:
When you connect a drive locally, Time Machine stores backups for
your computer in a folder like this:
And, inside that folder, you'll find a date- and time-stamped folder
for each individual backup Time Machine is currently storing.
By contrast, when Time Machine backs up a Mac over a network, it
puts a sparse bundle disk image at the top level of the volume whose
name is similar to your computer's name, for example:
