Looking for faster network backup?

[ozgurerdogan]

I tried nfs backup but different switches but it is slow compared to uual backup. For example when I scp a backup to a different node, it is fast enough but not nfs. So looking for alternative way to store backups directly to a different machine.

Can I mount a remote bak as ssh mount and attach that directory to storage? Will it be as fast as manual scp? Or what is your suggestions?

Hi,
why is your nfs not fast enough?
I have on one cluster an nfs-share (exported from the third quorum-node) and the speed is ok - also with gigabit.ethernet:

INFO: transferred 10737 MB in 57 seconds (188 MB/s)
INFO: archive file size: 1.37GB
INFO: Finished Backup of VM 210 (00:00:59)

OK - this must be done bye caching but also dd shows good values:

dd if=/dev/zero of=/bckup/bigfile bs=1024k count=8192 conv=fdatasync
8192+0 records in
8192+0 records out
8589934592 bytes (8.6 GB) copied, 92.7322 s, 92.6 MB/s
