  • Nimble storage integration with Nimesa
    In my company, one of our prospects is running an on-premise vSphere data center and the storage is backed by HP Nimble I got the access to their environment to integrate Nimesa with Nimble storage, Earlier I integrated Nimesa with multiple storage servers like Nexenta, DDN IntelliFlash, InfiniDat and Pure Storage. Nimble REST API With my experience of integrating with multiple storage vendors, I planned to complete the integration work in a couple of days, and some testing for a week. Nimble is exposing REST APIs and the document for our targeted Nimble Storage Version 4.5.2.x version is available online…
  • Application consistent backup of Oracle database
    One of our POC customers has few Oracle databases running in their datacenter, they wanted to create application-consistent backups of their Virtual machines running Oracle server using Nimesa. Read more about What is application consistent backup Nimesa has tight integration with Microsoft SQL Server, users can create application-aware backups and restore up to table level but the same level of integration is not available with Oracle. In my earlier post, I mentioned how we can create an application-consistent backup of the MySQL Database using the pre and post script hooks in Nimesa, read here In this post, let us see,…

  • AWS Storage Gateway
    The data is moving to the cloud, many enterprises are moving to the cloud in full swing. Instead of refactoring the whole set of application companies start their cloud journey with Lift and shift and few organisations are using multi-cloud. If you are using a hybrid cloud and wanted to use the cloud volumes in your on-premise data centre, you can use the AWS Storage gateway’s virtually unlimited storage. Storage gateway is the hybrid cloud storage solution which is deployed in the on-premise environment and utilizes the cloud storage like EBS, S3 and Glacier and access it through the virtual…
  • Backup the Encrypted EBS volumes to DR Region / cross-account DR
    Amazon EBS encryption offers a straight-forward encryption solution for your EBS resources that don’t require you to build, maintain, and secure your own key management infrastructure. It uses AWS Key Management Service (AWS KMS) customer master keys (CMK) when creating encrypted volumes and snapshots. Encryption operations occur on the servers that host EC2 instances, ensuring the security of both data-at-rest and data-in-transit between an instance and its attached EBS storage. You can encrypt both the boot and data volumes of an EC2 instance. When you create an encrypted EBS volume and attach it to a supported instance type, the following…

  • Application consistent protection of MySQL databases: Nimesa approach
    Nimesa supports application-consistent backup of MSSQL databases with the recovery options from instance to table level. Recently we launched the MySQL application consistent backup to the beta customers Application consistency or transaction consistent backups of the Microsoft centric applications like ADDS ( Active Directory), MSSQL and MS Exchange are possible with the use of Microsoft’s Volume Shadow copy Services aka VSS. Most of the Storage provider build VSS- Hardware Provider to directly take a LUN snapshot of the array after the data flush. During the backup ( the point the snapshot is created ) backup vendors are able to interface…
