StarWind took into account disadvantages of offloading backups in public cloud and developed the solution which keeps backups safely and cost-efficiently both on- and off-premises. StarWind’s take on building a rock-solid backup environment Reduced costs in comparison with on-premises storage boxes (depends on the required storage amount, service plans, etc.)Īccessibility (data is assessable from any location connected to the Internet) Risk of service interruption/termination (bankruptcy, not-met SLA, problems with authorities, etc.) Security concerns (data is moved to an infrastructure owned by 3 rd party)Īdditional reliability (cloud providers replicate the data or make own backups) Simple management and low administration costs Network bandwidth and latency often are the main bottlenecks Ok, let’s say, there is a local copy on NAS and a copy on an on-premises virtual tape library, but you still need a copy off-premises anyway in order to meet the 3-2-1 backup plan! Why don’t you use public cloud as a remote location? Keeping your data in the cloud has certain pros and cons: Advantages
In this way, if an IT department is on a tight budget, or there isn’t enough space in a datacenter, you need a good alternative to physical tapes – virtual tape solutions. These systems also may need skilled engineers to maintain them that adds even more to TCO. Even though digital tapes have the lowest $/GB among backup media, digital tape systems are expensive and may require additional investments to be installed. However, there’s a small thing about tape-centric backup environments: their TCO may still be very high. For keeping data locally, everything seems clear: one copy resides on something like NAS or file/backup server while another is kept on some removable medium like tapes.
StarWind engineers follow well-known best practices and recommend sticking to the 3-2-1 backup strategy – a backup rule saying that there must be three copies of data on two different types of media with an extra copy stored in a remote location.
How can you make sure that your data are safe? Today, we discuss how you can build a rock-solid backup infrastructure to avoid making mistakes of my buddies. These guys learned a lesson: since that time, they always have a couple of daily backups distributed over different locations. The questions rather are how many backup copies do you have, and where is it better to store them? I remember some of my buddies not sleeping at short summer nights in 2017 because of WannaCry and Petya. I hope everyone who reads this backs up data.
