How are you connected to the drive? If it is over wireless, you should connect with an Ethernet cable instead. In any event, it shouldn't take two days. If you are using wireless, connect with Ethernet and then reboot. That will start a new re-index task that hopefully should finish in a couple of hours.
On my backupdrive is about 3TB stored.
Its a Western Digital 4TB My Book drive connected via FW800 to my Mac mini Server.
My 3 Computers are backuped there. One of the back up is from my Mac mini Server. Only this one has problems and keeps indexing.
After an other Reboot also Spotlight is now indexing (again?) this backupdrive. I wonder how long this may last now.
Timemachine is Backing up again. What i have done:
Started Festplattendienstprogram (Harddisk Repair Program) and performed the check. The result was ok = green. (Like Pondini proposed, thanx!)
I stopped Timemachine by performing a reboot.
I deaktivated Timemachine backup.
I ereased the "Backup-in-progress-file" in the Mac mini Servers backup.
I started an manual Backup and this went ok.
After that i restard automated backup again.
So im am fine now!
Thanxs to everyone.
I have checked your pages but have not been able to find the answer to my problem.
Since I upgraded to Lion more than a week ago, my computer is significantly slower (slower startup, slower opening of programs, slower switching from one program to another). It seemed a bit better after spotlight completed indexing of the computer, but it's still very slow now.
It's a MacBook Pro beginning of 2008 (I have 2GB of RAM, maybe that's not enough, but from the posts that I have seen, people seem to be running lion easily with 2GB...). I did not do a clean install but installed over Snow Leopard which was the original OS that was on the hard disk (which I had to replace probably 2 years ago).
Anyway, the only flagrant abnormal behaviour I can see as a non IT specialist is never ending time machine indexing of the backup (on an external HD almost continuously connected via USB) which I never had under Snow Leopard. I had the vague impression that Lion was faster when there was no backup / TM indexing under way, but I am not sure since I also had slower behaviour without the disk being connected.
Backup does complete after a long time (sometimes before the new hourly backup, sometimes not), however.
I checked the integrity of my backup disk with disk utility and it "appears to be OK".
Anyway, my questions are
(1) Could the indexing be responsible for slow Lion?
(2) Is there anything I can (or should) do about it?
Thanks already for your wisdom :-)
Since you've already repaired your backups, it sounds like the index is damaged.
Either erase the TM disk and let Time Machine start fresh, or,
Delete the index: First, download the Tinker Tool app, per #A3 in Time Machine - Troubleshooting. Follow the instructions there to show invisible files.
Open the TM drive/partition via the Finder. At the top level you'll find a .Spotlight-V100 folder. Delete it (you'll have to enter your Admin password), and empty the trash. Do not touch anything else.
Run a backup. The first one will take quite a while, as it must be indexed, but thereafter, backups should run normally.
