Time machine no longer working

Try a "full reset" of Time Machine, per #A4 in Time Machine - Troubleshooting.

If that doesn't help, see #A1 there to get the messages from your logs, then copy and post them here.

It sounds like your backups may be corrupted. Try repairing them, per #A5 in Time Machine - Troubleshooting.

If that doesn't help, see #C9 there to (of all odd things) try shortening some names.

It's an issue with Lion. An updated computer with 10.7 can't access the Time Capsule while another with Snow Leopard has no problems using it.

It's not a general problem with Lion.

But if you mean two Macs can't acces the same sparse bundle at the same time, that's true (and is not new with Lion).

Let me be more specific 🙂

A Macbook Pro was installed from scratch with Lion yesterday. After everything was configured, that computer could not "Enter Time Machine" located in a Time Capsule and it returned the same error as above, -6584. However, another Macbook Pro with Snow Leopard can "Enter Time Machine" without any problems. As you indicated, it's not a general problem with Lion, but this problem just happened with Lion installed. I read yesterday about some incompatibily with Lion and Time Machine regarding network drives but Time Capsule was not mentioned there. And those network drives needed to be firmware updated.

Are they both looking at the same backups?

If 2 Macs are backed-up to the same Time Capsule, there's a separate sparse bundle disk image for each one, named <ComputerName>.sparsebundle. Enter Time Machine will look at the backups of the Mac it's run from.

It sounds like the backups for the Lion Mac are damaged/corrupted, thus the recommendation to repair that sparse bundle.

Correct; that has nothing do do with this situation.

The Lion MB has not made any backups in the Time Capsule. It's just trying to access it for the first time. When "Enter Time Machine" option is used, the error comes back.

Thanks.

Ah, then see if there's a sparse bundle for it already (created when you set up Time Machine to back up to it); if so, delete it, per #Q5 in Using Time Machine with a Time Capsule.

Connect via Ethernet cable for the lengthy first backup,per #Q1 in the same link.

Thanks for the help. On the MB with Snow Leopard did an in place upgrade and could access the TC. The other MB that could not access was installed with Lion from scratch and the info transferred back and it could access the TC also. Weird but both MB work with the TC now and it was not configured at all.

Have a good evening.

Cool. Glad it's sorted out!

hello every one, am having the same code error 6584 with my time machine through Lion ugraded MBP, please help.

Many Thanks

So there is no solution for resolving this issue with out erasing previous back ups ?!!
