Backing Up on VMware

VMware Consolidated Backup (VCB) was released last June to make backup easier on a VMware platform. That was followed by a cackle of vendor announcements outlining their support for VCB as well as various ways they could improve upon it. Some wondered, therefore, was there something wrong with VCB itself?

Interesting article about backing up in vmware.  This is always a decision making process, whether to use another vmware product to manage the backups, or whether to plug straight into your legato/tsm backup solution, either way should work fine, the next decisions”:

What do you want backed up? – The whole ESX server? – Just the virtual machines?

How long should be the retention period? – 1yr, 1 month? – This is going to vary from machine to machine, from production/development

Keep in mind how you manage this from a backup level.  Say an ESX server or a virtual machine fails its backup, who handles that?  The team managing the backup infrastructure?  The wintel/linux/unix guys looking after the virtual sessions?

Also, what’s the SLA, the agreement on virtual machine backups against your physical servers, should a virtual machine have less retention period than a physical environment?
