BUSINESS CONTINUITY ASSESSMENT
Backup Requirement Assessment and Review of Current Backup Strategy
Assessment of Existing Implemented Backup Solutions
Assessment of Backup Infrastructure
Virtual or Physical machine backup and recovery is a 1/0 intensive task; meaning production workloads may suffer if the backup infrastructure is under provisioned or misconfigured. Infrastructure bottlenecks may affect backup and restore times as well as disrupt the production.
Assessment of Backup Storage
Backup storage is an important part of the backup infrastructure and deserves a closer look. Lower end home NAS devices or other general consumer electronics are sometimes used to store business data because of the affordability of such products. Cheap storage, however, may not be reliable under 1/0 intensive workloads and may lead to a backup file and backup metadata corruption.
Restore point objectives and restore time objectives dictate what type of storage is more suitable for a specific disaster recovery scenario. Deduplication appliances, Linear Tape-open devices, Directly Attached Storage, Network Attached Storage, S3 compatible Object Storage may be chosen depending on required RTOs and RPOs.
Backup Restorability Testing
It is crucial to conduct periodical test restores for required workloads as there are many reasons successful backups in some rare cases may still lead to unsuccessful restores: backup file corruption, backup storage malfunction, pre-existing machine file system corruption, malware caused operating system files corruption and in some “unicorn jumping over the rainbow” scenarios backup software bugs.
Offsite and Air Capped Backup Configuration
3-2-1 backup rule is commonly implemented for business critical data, the rule recommends three copies of backup files to be created, where two of the copies are stored on different storage media types, one of the storage media may be air gapped, and one copy is kept offsite.
Instant VM Recovery
Entire VM restores can take time depending on the restore scenario making the end user wait for the machine to become available. Instant VM recovery allows the VM to be accessed immediately in a matter of seconds running directly from the backup file. This VM can be later migrated to the production during the off hours.
Site Replication and Test Failover
Workloads can be replicated to a DR site and be available at a stand-by. In case of a disaster recovery scenario the available machines can be failed over to the DR site providing continued availability to the end user, once the production site is restored, changes made to the VMs on the DR can be failed back and the operations can be resumed as normal.
Cloud Backup and Cloud Replication
Small businesses may not have access to an offsite location or to an entire DR site, in this case a small fee can be paid to a contract for renting the right amount of storage processing resources to host offsite backups or replicas.
Automated Backup / Replica Testing in Insolated Virtual Labs
Manual backup/replica restorability tests are often overlooked as these tasks can be time consuming for the staff and resource intensive for the live environment. Automating backup restorability testing is the solution that allows IT administrators to focus on other tasks, while allowing automation to perform the actual backup restorability tests during the off hours, when the live environment is not heavily used by the end users.
Granular Item Recovery / Restorability Testing
Restoring an entire VM is a resource intensive task and not often required as most of the time users might only need a single item to be restored whether it’s a file, an email, an Active Directory item or an SQL database. It is important to take into consideration the backup software functionality to avoid staging operations overheads(???)
Backup for Cloud Workloads
Veeam Backup for AWS is a solution developed for protection and disaster recovery tasks for Amazon Elastic Compute Cloud (Amazon EC2) environments.
With Veeam Backup for AWS, you can create image-level backups of EC2 instances and keep them in Amazon Simple Storage Service (Amazon S3) for high availability, cost-effective and long-term storage. In addition to image-level backups, you can protect your data by creating and maintaining a chain of cloud-native snapshots of EC2 instances.
Meet disaster recovery compliance requirements – generate and automatically update documentation for DR procedures to eliminate the problem of outdated DR plans.
Automate DR procedures- create workflows that orchestrate failover and restore operations for Veeam Backup & Replication backups and replicas.
Prove recoverability – build test schedules to automate verification of failover and restore plans, with isolated and low-impact testing of VM backups, replicas and applications they run.
