I got the idea for this post from a Twitter thread. I thought such discussions were dead but clearly they’re not, and decided to shed some light on this, having dealt with backup at insane scale in a previous life.
It doesn’t matter what a feature is called – can you use it to recover? And, if the answer is yes, how quickly and under which scenarios? And what are the downsides?

Sometime last night/this morning a config file in my blog got corrupted. Maybe it got hacked (I was running an ancient WordPress version 2.1) but at any rate the site was down.

Before all the variable-block aficionados go up in arms, I freely admit variable-block deduplication may overall squeeze more dedupe out of your data.
I won’t go into a laborious explanation of variable vs fixed, but, in a nutshell, fixed-block deduplication means that data is split into equal chunks, each chunk given a signature, compared to a DB and the common chunks are not stored.

It’s been a while since I wrote anything – unlike some, I actually have a day job and don’t use ghostwriters! Well, at least that’s my excuse.
My admiration for RecoverPoint is well known (see older post, which is referenced internally within EMC as a great pro-RecoverPoint article). It really is a good product and, next to VMware, my favorite EMC acquisition.

So, let’s talk about this not-so-hypothetical customer… They have:
- A few sites
- A lot of data per site
- Much of the data is DBs and Multimedia
- No replication currently
- Can’t back up everything currently
- No proper DR
- Fairly significant rate of change
- Not the fastest pipes between sites
They asked me to propose a solution that will back everything up and cross-replicate the backups between the sites. They want to move as far away from tape as possible.
