It’s true. CDP is tremendous technology, offering granular point-in-time restore that backups simply cannot do. But CDP (Continuous Data Protection) has severe retention and data management limitations, so backup is absolutely necessary.
But – why do CDP if you cannot get it FULLY UNIFIED with your backup solution?? I don’t mean “integrated”. Any moron can “integrate” a CDP product with their legacy backup product (and, many have, mind you). You just tell the people in marketing to make the box look the same, and update the user manual.
THE TRUTH: CDP is ONLY worth doing, if it comes FULLY UNIFIED with a next-generation backup solution (optimally, with inherent deduplication). That way, they share the same data mover, the same repository, the same metadata, the same underlying data structure and supporting infrastructure.
I dont know any other product besides Cofio’s AIMstor that does this. You get granularity of CDP, with smart retention flexibility of AIMstor’s next-gen Backup, and all the great policy driven capabilities that come together with it. You can also empower Bare Metal Restore from your backup and CDP sets, which are fully single-instanced for huge capacity savings.
More importantly, because AIMstor auto-classifies data, you can SELECT what you want to CDP, and what you want to Backup, and what retention you want for very specific types of data, or whole categories of data. Standalone CDP products are kinda, well, dumb. They like to move . . . everything. Optimal? Uhm, not.
So what happens if you buy CDP that is NOT unified with your backup solution? Triple the data movers, double the repository setup and capacity usage, double the overhead to servers and clients, double the admin time, double the infrastructure. Plus, you probably can’t select what you really want, so you will just end up wasting even more resources. Why do it?
