backup strategy to setup for your office, are you asking the right questions? Do you take into account Recovery Time Objective (RTO) and Recovery Point Objective (RPO)? For instance, with regards to RTO, have you asked yourself the following: If I had a complete failure of my servers and access to data, how long can I be down without affecting my business? Whatever your answer is, that is your RTO.
The other question to consider: Say your current backup takes place at 11pm every night, and you come into the office the next morning then at 2pm the server crashes on you. What happens to the data that took place from the time you got to the office in the morning to the time the server crashed, how easy is it for you to recreate it? This data will not have been backed up because the most recent backup took place at 11pm. You have to consider how long can you go in your day where you are not able to recreate the entries. 1 hour? 2 hours? 8 hours? Whatever your answer is, that is your Recovery Point Objective (RPO).
Now having this information in hand, you need to compare what your objectives are to what you have in place. If you have a tape backup in place, your RTO is most likely from 1 day to 5 days and your RPO is from 8 hours to 24 hours. If your business can stand being down that long and your employees can stand not doing work for that long, you have the right solution in place. If however, you are like most businesses today, this is not realistic. Your RTO and RPO are much smaller.
Fortunately, today there are solutions that you can implement that will NOT break the bank and give you a 2 hour RTO and RPO. The technology I am referring to is snapshots. The newest options for backup now include the capability to take a snapshot of the full hard drives and allow you to fully recover to dissimilar hardware in a very short time. If you need a shorter recovery time, there are other options that are available; however, the shorter the RTO and RPO, the higher the costs start to get.
"I come in tomorrow morning to find that my systems are down, now what? Who do I call and how long will it take me to get my systems back up?" This situation is a very real possibility that may even have happened to you already. Are you prepared with the backup strategy you need? - If the answer is not a definitive yes, contact us to change that.
