I’m having a few issues with Time Machine. I’ve noticed that backups seem to be getting progressively slower. Details are:
System: 17” 1.25Ghz iMac – PowerPC – 10.5.8
Data: Around 140GB total data over two hard drives:
1st Drive: Internal hard disk
2nd Drive: Smartdisk CrossFire External Firewire 400 Hard Drive
Time Machine Drive: LaCie d2 Quadra Firewire 400 Hard Drive
Time Taken for Incremental backup: Between 6 and 13 minutes, usually around 10 minutes.
I’ve tried all the usual things – permissions repair on all drives, deleting the V100 spotlight file on the TM drive in order to rebuild the spotlight database, I’ve tried copying files directly to the TM dive to check the firewire connection and it’s lightening fast.
A few days ago I even resorted to re-initializing my entire TM drive, zeroing it out and starting again completely.
At first this improved things slightly. Before I started again, my backups were taking 20 minutes plus, but afterwards it went down to between 6 and 8 minutes, but now it’s slowly creeping up again.
In terms of data, all I’m doing is checking emails and using the web and maybe the odd word processing. I haven’t done any heavy video editing for ages and don’t download music or movies so there aren’t massive amounts of data flying about. Backup sizes are often as low as1.5 megabytes.
Before I started having these problems, I’m sure a standard incremental backup would take little more than one minute and often even less than that.
So what can I do to fix this? The system really grinds when TM is backing up which is fine if it’s for one minute but a real pain if it’s spending 15 or 20 percent of the time churning though backups.
Any help or advice gratefully received.
