when you're doing a backup?
This is with rsync at bwlimit=2500
This is doing the same transfer with SSH. The load still climbs...and
then load drops. I think NFS is the issue.
I wonder if my NFS connection settings in client fstabs are unwise? I
figured with beefy machine and fast networking, I could take
advantage of large packetsizes. Bad packet sizes?
Are you backing up nfs to nfs? From where to where are you doing
backups?
The source data is on a ext3 partition, LVM volume, backed by a 15krpm
raid 10 volume. Both rsyncs where conducted from the source host (the db
server) to the backup server (which hosts nfs). In the nfs backup, I was
rsyncing from the db filesystem to an NFS mount, and the ssh backup, I
was rsyncing from the db filesystem to [EMAIL PROTECTED]:/backups.

Ok, so the DB is residing locally on the local server you are copying
onto the nfs mount only during backup?
