I dont get the controversy here. Every single agentless backup uses snapshots, always has. Veeam, Unitrends, etc. How else could they work?
edit: For example, I can do a snapshot in XS/xcp, then export that snapshot. That is a real agentless backup. This is exactly the same process Unitrends uses, with a bit of flair added on like dedup and some other stuff like automation.This is actually incorrect. There have been agentless systems that can mirror data without using a snapshot by leveraging write splitting technology. RecoveryPoint was an early one in the physical layer (and similar storage virtualization engines). VAIO based replication (RP4VM's, Veritas) also can replicate without a snapshot as the API's allow for write splitting to occur at the hypervisor layer giving you access to a "journal" and window you can recover from.
You may use snapshots, or scripts to stun applications WITH these technologies to improve consistency of recovery, but they have existed for a long time and can run without snapshots.
Uhhuh. What is the cost of these solutions? Hundreds of thousands of dollars? Millions of dollars? This is an SMB IT admin forum, not Fortune 100 IT Admin forum.
Any of the solutions you mention here are meant for huge shops with annual multimillion dollar IT budgets.
I could give you specifics, but like all IT products, the price is hidden until you talk to someone on the phone.
I doubt anybody here on this forum is in an environment where these would be considered. One of the examples I see on the web for one of these products is for 2500 vms.
None of them work with anything other than VMware.
