Re: Odd Time Machine error message
Hi Dennis, For each backup that TM performs, it adds about 20% for workspace. I don't understand this. 20% of what? TM adds about 20% for padding for workspace it needs on the TM disk. So if you are backing up 200GB + 20% workspace = $240GB Cheers, Ronni On 15/06/2009, at 11:52 AM, Dennis Barnden wrote: Ronda Brown Fri, 12 Jun 2009 22:02:31 -0700 On 11/06/2009, at 9:57 PM, Dennis Barnden wrote: Time Machine has reported an error with the message This backup is too large for the backup volume.

Hello Dennis, You don't mention what size your internal harddrive is what size the external drive you are backing up to is? The internal drive is 300GB and the destination is 500GB but that is really not an issue. TimeMachine has been working since January without problems and is working still. I got that one error message that had the required size of 1GB but an available size four times that size. And the Finder reported twice as much again. For each backup that TM performs, it adds about 20% for workspace. I don't understand this. 20% of what? The recommended size of a TM drive is at least 2x to 3x the size of the internal drive. Cheers, Ronni I just had a thought (dosen't happen often) If the destination is full and TimeMachine delets the oldest backup then there is a potential increase in available space on the destination so that might explain the larger Finder report but the initial TimeMachine error still seemed to want less than what it said was there. Why would that be a problem? This is for interest only as all seems to be working fine now.
