But backups need to be stored offsite, just in case. For faster recovery, local backups can be handy as no time is spent downloading the files from some other site. It is always advisable to not only keep your backups in the same data center as your database so as to reduce the likelihood of the backups being destroyed simultaneously. The plan or policy should include enough measures to secure the backup from various types of malicious attacks. Having a good database backup plan and policy is important in any organisation. The expired backups should be automatically purged. Your backup policy should account for the possibility that different types of data may have different retention policies – depending on compliance and business requirements. how long you want keep to your backed up data. There should be a mechanism to ensure adherence to your Retention Policy – i.e. Mechanisms may include email, or notifying via Slack or PagerDuty. Your backup implementation should provide timely notifications for critical events such as backup failures. But if you are archiving your backup files with a cloud storage vendor, encryption is not optional.ĬlusterControl provides a complete backup management solution, by scheduling different types of backups, providing reports, archiving to public cloud locations, encryption, compression, retention and automatic restore verification. Just like compression, keep in mind that encryption has a computation cost both during backup and recovery. While backing up your cloud database you need to consider whether encryption of your data is required. Security of your cloud database is a key consideration while implementing a backup solution. Your backup implementation should seamlessly integrate such pre-backup and post-backup checks. In some cases, you might also want to automatically verify the newly taken backup before removing an old backup file. At the other end, a post-backup can remove old backup files based on the retention policy after a successful backup has finished. A pre-backup needs to check whether the needed storage will be available for the upcoming backup run. Backup catalog should be automatically kept up-to-date to keep track of all copies of backup images. Backups must be taken consistently and regularly, relying on human intervention should be avoided. How will you manage your backup process and backed up data?īackups should always be automated. Depending on these factors and the requirements of the business, you will need to decide on the scheduling of your backup window. The size of your database and rate of transaction activity will determine how long your backup window will be. During the backup window, your applications can be degraded (in performance or functionality or both) or even offline. What will be the impact on your Application during the backup?īackup window refers to the time it takes for backups to complete. Therefore, you will need to determine RPO and RTO for hybrid cloud databases in your environment and implement your backup solution accordingly. You should carefully consider how long your application can be offline while you do a recovery. The Recovery Time Objective (RTO) defines how much time it will take to recover the database. How much time will you have to recover your database In some circumstances, you may want to selectively exclude some rogue transactions during the recovery process. In other words, how much data can you afford to lose? For example, if a user dropped a table by accident at 11:55 am, you might want to recover to a point in time just before the delete command. The Recovery Point Objective (RPO) defines what point in time you have to recover your database. To what point in time will you need to recover your database Just like planning any other backup implementation, the most important consideration is the recovery process. Considerations for Backing Up Hybrid Cloud Databases How fast and how easy is the recovery process? In this blog, we will look at some considerations for your backup strategy when it comes to redundancy, durability, data security, and data retention. But how do you handle database backups in a hybrid setup? Hybrid cloud databases are gaining adoption as a strategy for architectural resilience, agility by leveraging cloud resources but without necessarily being locked into one vendor’s cloud infrastructure.
