cjsogle Posted August 13, 2002 Report Share Posted August 13, 2002 I am backing up about 23gb from a Cube to a firewire drive. I am getting throughput of around 11MB/min. The backup has been going 24 hrs and is not even half way through copying, never mind verification!!! Does anyone have any ideas? Thanks Link to comment Share on other sites More sharing options...
Drishmung Posted August 13, 2002 Report Share Posted August 13, 2002 Have you ever backed up to this drive before? I.e., has it suddenly started being slow? What's your system? What sort of drive is it? Have you looked at the console or system logs to see if any errors are being reported? Does Retrospect report any errors in its log?

cjsogle Posted August 13, 2002 Author Report Share Posted August 13, 2002 Answers to some questions: System:G4 450mhz Cube with 512 ram Internal 80gb 7200 Western Digital drive External Maxtor 80gb 7200rpm firewire drive. I have not backed up this drive before. It is completely rebuilt after a major OS X crash. The external is also completey re-initialized. Have checked contents with both Norton and Drive 10 - all OK (with the exception of the usual Norton 'major error' errors!) I have not looked at the logs yet as it is still backing up. The total by the way is 34gb not 23 but it is now 32 hours later and it has completed 22 with 14 to go at a current rate of 12.3mb/min.... Help! This is crazy stuff! Thanks for the interest!

Mayoff Posted August 13, 2002 Report Share Posted August 13, 2002 The original question was a little unclear. Is this a local backup or a client backup? If local: What is the speed when writing to a file backup set? If Client: If you "get info" on the client from Configure>Clients client database what "speed" is report for the connection?

cjsogle Posted August 14, 2002 Author Report Share Posted August 14, 2002 This is a LOCAL backup direct to external firewire disc. It is backing up at around 10mb per minute. This is with compression OFF. Any ideas Mayoff? Thanks in anticipation Link to comment Share on other sites More sharing options...
Drishmung Posted August 14, 2002 Report Share Posted August 14, 2002 You can look at the logs even while the backup is happening, even the Retrospect ones. The view log menu item should still be available. Looking at the system and console logs of course you can always do. Link to comment Share on other sites More sharing options...
Mayoff Posted August 14, 2002 Report Share Posted August 14, 2002 A local backup to a FireWire hard disk (I assume using a File Backup Set) should be getting 30+ MB per minute. I get over 50 at home. What speed do you get if you save the file backup set to the internal hard disk as a test? If you can quickly back up to the internal hard disk but get very slow performance to the FireWire disk, then that is a clear indication of 1) A device communication problem, 2) a problem with the device. 1) Try with basic Mac OS Extensions 2) Try defragmenting the FireWire hard disk 3) Try changing the Firewire cable 4) Try the Firewire drive on a different Macintosh 5) Make sure the Mac has the latest firmware installed Link to comment Share on other sites More sharing options...
cjsogle Posted August 14, 2002 Author Report Share Posted August 14, 2002 Hi Robin Thanks for the response. After 37 hours of processing, we had a power out here. It apparently corrupted the Storage Set so I had to start again.....that was 7.30 yesterday evening and it is now 3pm and only a measly 11.7 Gb are completed out of the total of 36GB. Needless to say I am reluctant to stop it in order to check backing up to the internal drive. I will however do this once the backup is complete but at this rate it will only be tomorrow sometime. I will report back then. It is sitting steady around 10/11mb /min currently. Thanks Link to comment Share on other sites More sharing options...
