Is it normal for the target of a backup to show 100% wait-io during a backup ?
Backing up a Linux (Debian Lenny) system with about 1.6G in 55k files
to another Debain Lenny system running nothing but rdiff-backup, I'm
seeing the remote end showing 99 or 100% wait-io and the backup
taking hours. The target directory is on an iSCSI volume, but a quick
check shows that the performance on that volume isn't hugely less
than a local hard drive.
The command running is :
rdiff-backup \
--backup-mode \
--exclude-globbing-filelist /etc/backup-excludes \
--preserve-numerical-ids \
--ssh-no-compression \
/ backup::/store/backup
Both systems are guests on a Xen host with a 4core 2.4G processor and
plenty of ram (the target currently has over 1G free). rdiff-backup
is ver 1.2.1
Any hints ?
