aschubow Posted October 5, 2005 Report Share Posted October 5, 2005 This is a continuation of the following thread, which has gone to 8 pages. user interface incredibly slow I am backing up a subvolume on the RAID. in the previous version the CPUs would be pegged when trying to back up the raid, even though not much was happening. Now CPU usage is minimal and not much is happening. haven't checked RAM usage. I will try to do an immediate backup on the whole volume and just select the folder I want. That's not really a long term fix, because the backup needs to run in a script, but it is definitely worth a shot to narrow down the issue. Quote: Alex, Can you please start a new thread for this. It is getting hard to keep up with the details here. What is CPU and RAM usage like when backing up the software RAID? Are you selecting the root of the RAID to backup or just selected folders? Do you a notice a difference either way? Thanks Nate Link to comment Share on other sites More sharing options...
michaeln Posted October 5, 2005 Report Share Posted October 5, 2005 Hi, Just to be clear, you are not booted off of the RAID and you are not seeing slow UI response with 6.1 right? This is an issue with slow backups when the RAID is a source volume. Can you explain a little about how your software RAID is setup? Are you using the RAID Admin utility to set this up? I'll see if I can get a hold of the necessary hardware to test this. Link to comment Share on other sites More sharing options...
aschubow Posted October 6, 2005 Author Report Share Posted October 6, 2005 Here is the whole setup. dual 1ghz G4 with 1.5 GB ram, running 10.4.whateveristhelatest server. booting off a 160GB raid made from a hardware card (this backs up at over 400MB/min) The UI is now fine with 6.1 (previously retrospect would eat tons of CPU cycles). Backing up a subvolume, or backing up a folder selected from the software RAID volume makes no difference. The backup chugs along at 12 or 13MB/min. The folder I want to back up is about 200GB, so as you can see, this is just not going to work. Retrospect uses almost no CPU during this time and very little memory (under 40MB real memory) The software RAID is made with SoftRAID. The reason I spent the money on SoftRAID is because I was hoping Retrospect would get along better with it than a RAID volume made with disk utility, but unfortunately this is not the case. The data on the volume has grown significantly since it was last backed up (nearly 500 GB now) so formatting it with disk utility to try that again is not an option, since I won't be able to restore my data. The last time it was backed up it had only about 100GB on the disk, and the backup ran for nearly a week. At that time it was formatted with disk utility. Thanks for looking into it. I need to get this working ASAP. I am living on borrowed time here. Link to comment Share on other sites More sharing options...
CallMeDave Posted October 6, 2005 Report Share Posted October 6, 2005 Quote: booting off a 160GB raid made from a hardware card... You don't mean a hardware _RAID_ card, but a hardware disk bus card (ATA, SATA, etc), right? So trying with an XServeRAID (which uses a hardware RAID controller) would be a different test.

natew Posted October 7, 2005 Report Share Posted October 7, 2005 Hi What version of softRAID do you have? 3.2.1 is the current version on version tracker. Thanks nate Link to comment Share on other sites More sharing options...
aschubow Posted October 7, 2005 Author Report Share Posted October 7, 2005 It is booting of a RAID 0 volume created on a hardware RAID card. The volume I am having problems with is a SoftRAID volume, running the latest version of the driver. I had identical problems with Retrospect 6.0 and the same two disks formatted into a RAID 0 volume with disk utility. Link to comment Share on other sites More sharing options...
natew Posted October 10, 2005 Report Share Posted October 10, 2005 Hi Can you tell me about the hardware involved in the software raid please? How are the disks attached to the machine? Thanks Nate Link to comment Share on other sites More sharing options...
CallMeDave Posted October 10, 2005 Report Share Posted October 10, 2005 Does the problem being reported happen _only_ when the machine is booted from the hardware controlled RAID 0 volume? I find it stunning that after 11 posts over 5 months, the make/model of this hardware RAID haven't ever been mentioned. It probably would have been good to have provided this information a few months ago, before Dantz finished the 6.1 update... Dave Link to comment Share on other sites More sharing options...
natew Posted October 11, 2005 Report Share Posted October 11, 2005 Hi I created a RAID 0 volume from two partitions on a firewire drive using disk utility. I selected one folder as a subvolume for backup. I saved the backup to a file backup set stored on the internal SATA drive. My backup speed was 458 MB /minute. There are no hardware RAID cards on this machine and the boot drive is a standard boot volume. At least on a basic level we know backup from a software RAID should proceed normally in Retrospect. Dave's question is key. Can you boot from a firewire disk or the Retrospect boot CD and run a test backup of the software raid?
