Will rsync copy extended attributes, ACLs, etc. reliably enough for Time Machine?
I am copying a TM backup to a new drive over USB by drag&drop per Apple’s recommendation. But since it is more than two terabytes, I am concerned about the risk of interruption.
If I try to resume with rsync -avAX
will Time Machine be able to continue using it? Another question/answer suggests I might have to ensure I have the latest rsync but will that be enough?
Rsync, with the -E option, will copy the extended attributes and ACL of a file. The man page for rsync states:
-E, --extended-attributes copy extended attributes, resource forks
-E, --extended-attributes Apple-specific option to copy extended attributes, resource forks, and ACLs. Requires at least Mac OS X 10.4 or suitably patched rsync.
