The ease with which technicians trained in Oracle, MySQL, and SQL Server can transition to PostgreSQL means no skills barrier for companies interested in adopting this technology. Data resilience is what off-site data backups deal with, and having a resilient data store is crucial to any company investing in big data.PostgreSQL is a relational database and, as such, is easy to use for anyone familiar with SQL and the administration of RDBMSs. The balance that companies should aim for is having an off-site backup that is far enough away from the site so that local disruptions wouldn’t affect it, but close enough so that the company can successfully restore operations within a 48-hour window. Conclusionīusinesses that use off-site storage for their Big Data needs have to be able to balance the cost of storing, transporting, and restoring that data against the distance and time that is required to restore that data. Furthermore, data backups take time and with data lakes, this time could run into the dozens, even hundreds of hours depending on the volume of data required. Additionally, having a data storage of such magnitude off-site could potentially result in hefty transport fees if the off-site location is far away. Large data lakes can take up a massive amount of space, and for off-site storage, this can be a significant concern in cost. The Importance of Setting Your Business up With a Disaster Recovery Plan Big Data Storage Concerns Off-site storage methods should take RPO into account since having a more regular backup period might benefit the company, although it may cost more. For worst-case scenarios, the backups are much longer, possibly a month or two. If a failure were to occur, the company could safely recover up to the last 24 hours’ worth of data. Most businesses perform regular backups within the 24 to 48-hour window. If a crash were to happen, how long could the business potentially operate before feeling the impacts of that lost data? The capability of the company to restore that data is their RPO. RPO is the tolerance a business has for data loss. Restoration Capability and Recovery Point Objective (RPO)Ī recovery point objective (RPO), as defined by Tech Advisory, is the point at which a business’ data is backed up and from which the company can quickly restore its data state. If you have a business in Dubai, it’s not worth having your backup somewhere in China, since restoration periods would be too ridiculous. Having a data storage center that is closer, maybe within the same state, can make resorting the business’ operating information much faster and thereby offer a tighter RTO. If these backups are shipped out once per day, then the company likely has within 24 hours to restore those backups to ensure the continuity of their systems. Some companies prefer to ship their off-site backup to a place that’s out of state using an express carrier. However, reasonable is a subjective measure. RTO is crucial to ensuring that a business gets its data back into its systems after a system-wide shut down within a reasonable window. Druva defines RTO as the amount of time allowable for a company’s backup to resume service to ensure minimal disruption in the business’ continuity. Recovery Time Objective (RTO) can be considered the efficiency of backup restoration.
