--- title: Deploy Tiger Bridge Continuous Data Protection, Archive and Disaster Recovery with Azure Blob Storage titleSuffix: Azure Storage description: Deployment, and configuration guide for running Tiger Bridge in ContinuousData Protection, Archive and Disaster Recovery configurations. author: dukicn ms.author: nikoduki ms.date: 04/05/2022 ms.topic: concept-article ms.service: azure-storage ms.subservice: storage-partner-integration # Customer intent: As a data management professional, I want to implement Tiger Bridge for continuous data protection and disaster recovery with Azure Blob Storage, so that I can efficiently manage data, optimize costs, and ensure quick recovery from data loss incidents. --- # Tiger Bridge archiving with continuous data protection and disaster recovery This article will guide you to set up Tiger Bridge data management system with Azure Blob Storage. Tiger Bridge Continuous data protection (CDP) integrates with [Soft Delete](../../../blobs/soft-delete-blob-overview.md) and [Versioning](../../../blobs/versioning-overview.md) to achieve a complete Continuous Data Protection solution. It applies policies to move data between [Azure Blob tiers](../../../blobs/access-tiers-overview.md) for optimal cost. Continuous data protection allows customers to have a real-time file-based backup with snapshots to achieve near zero RPO. CDP enables customers to protect their assets with minimum resources. Optionally, it can be used in WORM scenario using [immutable storage](../../../blobs/immutable-storage-overview.md). In addition, Tiger Bridge provides easy and efficient Disaster Recovery. It can be combined with [Microsoft DFSR](/windows-server/storage/dfs-replication/dfsr-overview), but it isn't mandatory. It allows mirrored DR sites, or can be used with minimum storage DR sites (keeping only the most recent data on-prem plus). All the replicated files in Azure Blob Storage are stored as native objects, allowing the organization to access them without using Tiger Bridge. This approach prevents vendor locking. ## Reference architecture :::image type="content" source="./media/tiger-bridge-cdp-guide/tiger-bridge-reference-architecture.png" alt-text="Tiger Bridge reference architecture."::: More information on Tiger Bridge solution, and common use case can be read in [Tiger Bridge deployment guide](../primary-secondary-storage/tiger-bridge-deployment-guide.md). ## Before you begin - **Refer to [Tiger Bridge deployment guide](../primary-secondary-storage/tiger-bridge-deployment-guide.md)**, it describes initial steps needed for setting up CDP. - **Choose the right storage options**. When you use Azure as a backup target, you'll make use of [Azure Blob storage](https://azure.microsoft.com/services/storage/blobs/). Blob storage is optimized for storing massive amounts of unstructured data, which is data that doesn't adhere to any data model, or definition. It's durable, highly available, secure, and scalable. You can select the right storage for your workload by looking at two aspects: - [Storage redundancy](../../../common/storage-redundancy.md) - [Storage tier](../../../blobs/access-tiers-overview.md) ### Sample backup to Azure cost model Subscription based model can be daunting to customers who are new to the cloud. While you pay for only the capacity used, you do also pay for transactions (read and write), and egress for data read back to your on-premises environment (depending on the network connection used). We recommend using the [Azure Pricing Calculator](https://azure.microsoft.com/pricing/calculator/) to perform what-if analysis. You can base the analysis on list pricing or on Azure Storage Reserved Capacity pricing, which can deliver up to 38% savings. Below is an example pricing exercise to model the monthly cost of backing up to Azure. | Cost factor | Monthly cost | | ----------- | ------------ | | 100 TiB of backup on cool storage | $1556.48 | | 2 TiB of new data written per day | $39 | | Monthly estimated total | $1595.48 | | One time restore of 5 TiB over public internet | $491.26 | > [!NOTE] > This is only an example. Your pricing may vary due to activities not captured here. Estimate was generated with Azure Pricing Calculator using East US Pay-as-you-go pricing. It is based on a 32 MB block size which generates 65,536 PUT Requests (write transactions), per day. This example may not reflect current Azure pricing, or not be applicable towards your requirements. ## Prepare Azure Blob Storage Refer to [Tiger Bridge deployment guide](../primary-secondary-storage/tiger-bridge-deployment-guide.md) ## Deploy Tiger Bridge Before you can install Tiger Bridge, you need to have a Windows file server installed, and fully functional. Windows server must have access to the storage account prepare in [previous step](#prepare-azure-blob-storage). ## Configure continuous data protection 1. Deploy Tiger Bridge solution as described in [standalone hybrid configuration](../primary-secondary-storage/tiger-bridge-deployment-guide.md#deploy-standalone-hybrid-configuration) (steps 1 to 4). 1. Under Tiger Bridge settings, enable **Delete replica when source file is removed** and **Keep replica versions** :::image type="content" source="./media/tiger-bridge-cdp-guide/tiger-bridge-settings.png" alt-text="Screenshot that shows how to enable settings for CDP."::: 1. Set versioning policy either **By Age** or **By Count** :::image type="content" source="./media/tiger-bridge-cdp-guide/tiger-bridge-versioning-policy.png" alt-text="Screenshot that shows how to set versioning policy."::: Tiger Bridge is natively integrated with [Windows Volume Shadow Copy Service](/windows-server/storage/file-server/volume-shadow-copy-service). Integration enables restoring files and folders protected by Tiger Bridge CDP using native windows tools, like Windows Explorer. To verify CDP is enabled, simply change any file and use Windows Explorer Previous Versions to verify a version has been created. You can restore any version listed by selecting it, and pressing **Restore**. :::image type="content" source="./media/tiger-bridge-cdp-guide/tiger-bridge-previous-versions.png" alt-text="Screenshot that shows how to verify a file is protected by Tiger Bridge CDP."::: Tiger Bridge CDP also enables restoring files if there was accidental deletions. To undelete a file, Tiger Bridge Shell extension can be used. Simply select the folder where the file was originally located, navigate to Tiger Bridge Shell Extension and select **Undelete**. :::image type="content" source="./media/tiger-bridge-cdp-guide/tiger-bridge-undelete.png" alt-text="Screenshot that shows how to undelete a file protected by Tiger Bridge CDP."::: ## Configure archiving Tiger Bridge can move a replicated file between Azure Blob Storage tiers to optimize for cost. That process is called archiving, and it replaces a file with an offline file (stub). To configure archiving, perform the following steps. 1. **Replicate data directly to Azure Storage Archive tier** - If you want replicated data to be automatically tiered to Azure Storage Archive tier, a **Default access tier** has to be changed in Tiger Bridge configuration. :::image type="content" source="./media/tiger-bridge-cdp-guide/tiger-bridge-pair-account.png" alt-text="Screenshot that shows how to pair a storage account with local source."::: Change **Default access tier** to **Archive**. You can also select a default **[Rehydration priority](../../../blobs/archive-rehydrate-to-online-tier.md)**. :::image type="content" source="./media/tiger-bridge-cdp-guide/tiger-bridge-change-access-tier.png" alt-text="Screenshot that shows how to change a default access tier in Tiger Bridge Configuration."::: 1. **Configure archiving policy** - Tiger Bridge allows you to specify which files on local source must be moved to archive tier. Policy can configure two parameters: 1. **Minimal file size** - specifies minimum file size for archiving. Only files with sizes larger than defined value will be tiered to Archive tier. 1. **Time interval** - specifies time interval in which the files haven't been accessed. All files that haven't been accessed in at least the defined value, will be moved to Archive tier. :::image type="content" source="./media/tiger-bridge-cdp-guide/tiger-bridge-archive-policy.png" alt-text="Screenshot that shows how to change an archiving policy in Tiger Bridge Configuration."::: Once the files are in Archive tier, they are not directly accessible. To access those files, they have to be rehydrated (moved from Archive tier to Hot or Cool tier). Tiger Bridge Shell Extension can be used to invoke the rehydration process in a simple way. Right-click on the file you want to rehydrate in Windows Explorer, find Tiger Bridge Shell Extension, and select **Rehydrate from Archive**. You'll be notified that **Restoring from archive (Rehydrate)** is an operation that may apply other fees. :::image type="content" source="./media/tiger-bridge-cdp-guide/tiger-bridge-rehydrate1.png" alt-text="Screenshot that shows how to use Tiger Bridge Shell Extension to rehydrate the file."::: :::image type="content" source="./media/tiger-bridge-cdp-guide/tiger-bridge-rehydrate2.png" alt-text="Screenshot that shows confirmation diagram for rehydration process."::: For more detailed information on how to configure Tiger Bridge for your specific set-up, refer to the latest [Tiger Bridge Administration Guide](https://www.tiger-technology.com/software/tiger-bridge/docs/) ## Configure disaster recovery Tiger Bridge can be configured in Disaster Recovery mode. Typical configuration is an active - passive configuration with one Tiger Bridge server on the primary and one on the secondary site. Tiger Bridge server on the primary site is active and replicates the data to secondary Tiger Bridge server (through Azure Blob Storage). Tiger Bridge server on the secondary server is idle and receives file changes :::image type="content" source="./media/tiger-bridge-cdp-guide/tiger-bridge-dr-active-passive.png" alt-text="Architecture for Tiger Bridge in active - passive DR configuration."::: 1. Deploy and setup Tiger Bridge server on the primary and secondary site as instructed in [Tiger Bridge deployment guide](../primary-secondary-storage/tiger-bridge-deployment-guide.md#deploy-standalone-hybrid-configuration) for standalone hybrid configuration > [!NOTE] > Both Tiger Bridge servers on primary and secondary site must be connected to the same container and storage account. 1. Enable Tiger Bridge synchronization on both Tiger Bridge servers. :::image type="content" source="./media/tiger-bridge-cdp-guide/tiger-bridge-dr-sync-policy.png" alt-text="Screenshot that shows how to enable Tiger Bridge sync policy."::: - On secondary Tiger Bridge server, disable **Listen**, and enter the time interval at which servers will check for notifications from active server about changes. - Choose if you want to automatically retrieve the changed files to the secondary server immediately. Selecting **Automatically restore files on the synchronized source** will download all the changes on the secondary server immediately. If unselected, changes will be downloaded on demand. - After the settings are done, click **Apply** For increased resiliency on the primary site, Tiger Bridge support Windows DFSR that would enable replication between two Tiger Bridge servers on the primary site. If there were issues with one of the Tiger Bridge servers on the primary site, other one would continue to operate. > [!TIP] > Tiger Bridge Policies and Synchronization can be defined as global (applied to all Tiger Bridge servers), or can be defined per Tiger Bridge server. ## Support ### How to open a case with Azure In the [Azure portal](https://portal.azure.com) search for support in the search bar at the top.
