Any reason to not use NBD?
-
Hi Everyone,
I was wondering if anyone could offer some insight or advice. I have recently turned on "Use NBD Protocol" option for my local backups and CR backups between various DC's.
I must say that I am very impressed with this option. Using a concurrency of 1, the conventional backups give me a 300Mb/s throughput between Data Centres and with NBD enabled, I get roughly 790Mb/s (over a 1Gb line). So.. YEA!!
I have also noticed that if I re-dimension a VDI, it dosent trash the entire backup, but seems to understand that the VDI had expanded and writes the new data in the current backup, so again.. YEA!!
But I was wondering.. Is there any reason to not use NBD? Having the option to enable or disable almost makes me feel as if there could be a potential downside that I am unaware of.
Thanks in advance,

The other perk is reduced CPU usage in your Dom0 too
Well, it works pretty good and I don't see a reason to not use it.
