This characteristic is presently in preview, please attain out to us if you’re involved in attempting it out. To be taught extra, confer with the documentation.
- Backup for big digital machine configurations – Along with supporting a big selection of Linux distributions endorsed by Azure, with Azure Backup you possibly can configure backup for digital machines with as much as 32 hooked up managed disks and a big disk measurement of as much as 32 TB. Now you can backup M sequence digital machines containing a write accelerator disk that runs low latency, and excessive transaction workloads like Oracle, SAP HANA, and so on. For extra particulars, please refer the help matrix.
- Versatile restore choices – Clients can restore to switch the supply digital machine or create a brand new digital machine from the backup. Other than these choices, prospects can select to revive particular information and folders from the backup as an alternative of restoring all the digital machine. For mission-critical workloads that demand excessive availability of backup information, buyer can carry out cross area restore within the secondary area within the occasion of a partial or full outage. Most occasions, prospects restore from the newest backup as a consequence of an incorrect deployment or corruption of knowledge. On this case, prospects can carry out an on the spot restore from the current backup that provides fast restoration time. You may confer with the entire out there restore choices within the documentation.
- Price optimization – Utilizing the selective disk backup characteristic, you possibly can again up a subset of the information disks in a digital machine offering an economical backup answer. Whereas configuring safety of the digital machine, you possibly can select to exclude or embrace sure information disks within the digital machine from being protected. You’re going to get price saving on the protected occasion payment whenever you go for the OS disk solely backup possibility. Backup storage price is calculated primarily based solely on the included disks, so that you get to save lots of on the storage price. To additional optimize your backup price, learn the weblog publish on 5 methods to optimize your backup prices with Azure Backup.
Agent-less backup for Linux workloads
Azure Disk Backup gives a turnkey answer that gives a snapshot lifecycle administration for managed disk by automating the periodic creation of snapshots and retaining it for configured period utilizing the Backup coverage. You may simply handle the disk snapshots with zero infrastructure price and with out the necessity for customized scripting or any administration overhead. This can be a crash-consistent backup answer that takes time limit backup of a managed disk utilizing incremental snapshots with the flexibility to configure a number of backups per day. Furthermore, it’s an agent-less answer and doesn’t affect manufacturing software efficiency. You may backup and restore each OS and information disk (together with shared disk), no matter whether or not or not they’re presently hooked up to a working Azure Digital Machine.
Key advantages embrace:
- Extra frequent and fast backups with out interrupting the digital machine.
- Does not have an effect on the efficiency of the manufacturing software.
- No safety issues, because it doesn’t require working customized scripts or putting in brokers.
- Price-effective answer to backup particular disk.
You should use agent-less crash constant Azure Disk Backup within the following Linux workloads situations the place the agent-based software constant Azure Digital Machine backup isn’t appropriate or possible.
- Commerce-off as a consequence of safety and efficiency of the manufacturing workload: In case your are executing customized pre and publish scripts and invoking freeze and thaw on Linux digital machine to get application-consistent backup, this places undue overhead on manufacturing workload availability. Or your group or trade regulation restricts putting in brokers as a consequence of safety issues.
- Linux cluster utilizing Azure shared disk: Azure shared disk is a brand new characteristic for Azure managed disk that permits you to connect a disk to a number of digital machines concurrently. Workloads deployed onto Linux digital machines cluster write the information to a shared storage like shared disk. Utilizing Azure Disk Backup, you possibly can configure safety for the shared disk.
- Backup the persistent volumes of Kubernetes cluster: Containerized functions working on a self-managed Kubernetes cluster or Azure Kubernetes Service (AKS) cluster use Azure Managed Disk as persistent storage. At this time, it’s a must to again up the managed disk by way of automation scripts which can be arduous to handle.
- Price environment friendly backup possibility for Linux digital machines: You will have a number of Linux digital machines with a single disk (i.e., a digital machine with simply OS disk and no information disk hooked up) which can be state-less machines say, hosts Webserver or, serves because the staging atmosphere with software configuration settings. You should use Azure Disk Backup as a cost-efficient backup answer to guard the OS disk. You may set off a fast on-demand backup earlier than upgrading or patching the digital machine or restore from backup to reset the staging atmosphere after a test-run.
