How do you backup your virtual machines?

We are running the free VMware ESXi. I am backing up my VM's using trilead. I have two nics in each ESXi host, Nic0 & Nic1.

Nic0 in all three ESXi servers is connected to a gig switch.
Nic1 in all three ESXi servers is connected to a separate gig switch.
And a Western Digital Worldbook is also attached to the second gig switch.

My average throughput when backing up my VM's seems to be 5 - 7MB/s or almost 20g an hour.

What do you use and how does your performance compare?

I think I heard Jason say something like:

We use backupexec on a separate blade, connected to our storage through
the same switch as our VM blades, via a 4GB port channel. The avg job
throughput is 3,735.12 MB/Min.

We do a file level backup via the remote agent as well as a VM backup,
2 separate jobs going to our 2 separate drives in our tape library.

Re: How do you backup your virtual machines?

I am using VMware server running on OpenSuSE.
I have a cronjob that suspends the VM and rsyncs to another
server. I also have a tarfile that gets created of certain filesystems
of note which also is rsync'd. I average about 10MB/s on a 100MB switch. I
think the limiting factor is the VMware virtual NIC...performance to me has
always seemed poor.

Are you getting 10 MegaBytes/sec or Megabits?
10 MBytes/sec on a 100 Mbit switch is excellent.
100Mbits = 12.5 MBytes

Re: How do you backup your virtual machines?

ghettoVCB to do crash consistent online image level backups, planning
on doing this on a monthly basis. And for servers that have their
content changing frequently, we'll also do a file level backup using
Backup Exec 9 - just about to move to Commvault Simpana 8.

Just in the process of virtualising a couple of our main servers which
we centralise our backups to, so don't have any firm performance
numbers, just know that it is similar if not a little better than our
current non-virtualised backups 🙂
