You can recover application data\nto the original location or to another server.\n\nBenefits of using the **Mount** and **Migrate Recover** feature include the\nfollowing:\n\n- Provides a near-zero RTO for data recovery back to the final storage destination.\n- Reduces downtime for server and storage migrations.\n\nDifferences between SQL Server and logical volume manager file system mount and migrate\n---------------------------------------------------------------------------------------\n\nMount and migrate capability is available for SQL and file system applications.\nThere are a few significant differences in the way mount and migrate was\nimplemented:\n\n- When a file system application has Logical Volume Manager (LVM) on it, the LVM can migrate data and Backup and DR leverages this capability during mount and migrate. However, SQL applications cannot migrate data. Backup and DR has built a custom migration process for SQL mount and migrate.\n- The LVM file system mount and migrate is a two-step process that has been implemented for clone and restore only. By contrast, the SQL Server mount and migrate is a full implementation involving the three steps of mount or restore, configuring migration schedule, and finalize migration.\n\nConfigure schedule for mount and migrate\n----------------------------------------\n\nUse the following instructions to configure migration schedules.\n\n- [Configure migration schedule for mount---restore---images](#restore-image)\n- [Configure migration schedule for mounted images](#mount)\n\n### Configure migration schedule for mount---restore---images\n\nUse these instructions to configure the migration schedule:\n\n1. Select an active image with an image state of **Mounted** or **Restore Mounted**.\n2. Select **Migrate** from the drop-down menu.\n\n The **Update Migrate Frequency** page opens.\n3. For **Frequency**, use the slider to define the frequency with which\n to schedule migrate jobs---in hours. The minimum value is one hour\n and the maximum value is 24 hours.\n\n4. For **Copy Thread Count**, specify the number of parallel copy threads to\n use, per disk volume, during the migration. The default value is four.\n\n5. Click **Submit**. You are prompted to confirm.\n\n6. Click **Proceed** to apply the configuration.\n\n7. You can see a success message after configuration is complete.\n\n8. Click **Okay** in the success dialog to the **Active Mounts** page.\n\n### Configure migration schedule for mounted images\n\nUse these instructions to configure migration schedule:\n\n1. Select an active image with an image state of mounted or restore mounted.\n2. Select **Migrate** from the drop-down menu.\n\n The **Update Migrate Frequency** page opens.\n\n If you selected a **Mount** image, you can see the following dialog.\n For a mounted image, you may see more options depending on the specific\n database.\n3. For **Frequency**, use the slider to define the frequency with which\n to schedule migrate jobs---in hours. Minimum value is one\n hour and the maximum value is 24 hours.\n\n4. For **Copy Thread Count**, specify the number of parallel copy\n threads to use, per disk volume, during the migration.\n The default value is four.\n\n5. In the **File Locations** section, specify whether you want\n to copy the database files to the same path as the source server,\n or to a new location. There are three options:\n\n - Copy files to the same drive or path as they were on the source server---default option.\n - Choose new file locations at the volume level.\n - Choose new file locations at the file level.\n\n If you select the second option---new file option at the volume\n level---you see a table with the source volume---cannot be\n edited---and target volume drop-down---which is pre-populated with\n the same value as the source.\n\n In **Target Volume** , select a target volumes from the drop-down\n list of all discovered file system applications. If needed, you can\n also type the volume, for example: ``M:\\`, or``L:\\\\Logs\\\\Log1\\`.\n\n If you select the third option---new file locations at the file\n level---you can see a table with three columns:\n + **File** : Cannot be edited.\n + **Source Location** : Cannot be edited.\n + **Target Location**: This is pre-populated with the same value as that of\n the source location, excluding filename.\n6. In **Target Location**, enter the new file location and make other\n modifications as needed.\n\n7. Click **Submit**. You are prompted to confirm.\n\n8. Click **Proceed** to apply the configuration.\n A success message displays after the configuration is complete.\n\n9. Click **Okay** in the success dialog to the **Active Mounts** page.\n\nReview the following pages for more information:\n\n- [File system mount and migrate](/backup-disaster-recovery/docs/access-data/filesystem-mount-and-migrate)\n- [SQL Server mount and migrate](/backup-disaster-recovery/docs/access-data/sql-server-mount-and-migrate)"]]
