Everyone, I am running a backuppc installation with a pool around about 3.5TB. The biggest share in this pool is around 2TB and is located on the machine itself, so I use the tar method on localhost to back it up. When I do full backups of this share it takes around 4 days to complete and it seems to be only creating around about 10 small files every 20 seconds in the pc/localhost/new directory. This seems very slow.
It is not a disk problem or hardware throughput problem because a) I'm not using compression and b) and there is no disk activity. The CPU usage for BackupPC_tarExtract is constantly at 100% or thereabouts. The tar process that is creating the tar file is largely idle. The disk system is a RAID5-EE with 13 non-parity disks and it is formatted to ext3. So my question is twofold: What could be causing this problem? Is there a way of profiling the script so that a bottleneck could be identified? Thanks in advance, Chris. -- Dr Christopher Adamson, PhD (Melb.), B Software Engineering (Hons., Monash) Research Officer Developmental and Functional Brain Imaging, Critical Care and Neurosciences Murdoch Childrens Research Institute The Royal Children’s Hospital Flemington Road Parkville Victoria 3052 Australia T 9345 4306 M XXXX XXX XXX E [email protected] www.mcri.edu.au ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
