| CloudBacko Pro's Granular Restore technology enables the recovery of individual files from a guest VM without booting up or restoring the whole guest VM first. | CloudBacko Pro's Granular Restore technology enables the recovery of individual files from a guest VM without booting up or restoring the whole guest VM first. | ||
| - | Granular Restore is one of the available restore options for VMware ESXi/vCenter backup sets. AhsayOBM makes use of Granular Restore technology to enable a file level restore from a virtual disk file (VDDK) of guest VM backup possible. It is particularly useful if you only need to restore individual file(s) from a guest VM which would normally take a long time to restore and then startup before you can gain access to the files on the virtual disks. Granular Restore gives you a fast and convenient way to recover individual files on a guest VM. | + | Granular Restore is one of the available restore options for VMware ESXi/vCenter backup sets.

| - | During the Granular Restore process, the virtual disks of the guest VM can be mounted on the Windows machine as a local drive. This will allow the individual files on the virtual disks to be viewed via the file explorer within AhsayOBM or from the Windows File Explorer on the Windows machine you are performing the restore on, without having to restore the entire virtual machine. Granular Restore can only mount virtual disks if the guest VM is running on a Windows Platform and it is supported for all backup destinations, i.e. AhsayCBS, Cloud storage, or Local/Network drives. The mounting of Linux/Unix file systems from virtual disk file is currently not available due to limitations of the file system drivers. | + | During the Granular Restore process, the virtual disks of the guest VM can be mounted on the Windows machine as a local drive.

| ^ Cons | **No Encryption and Compression** - To ensure optimal restore performance, the backup of the guest VM will **NOT** be encrypted and compressed, therefore, you may have to take this factor in consideration when using this restore method. | **Slower Recovery** - As the entire guest VM has to be restored before you can access any of it’s file(s) or data, the restore time could be long if the guest VM size is large.\\ \\ **Two Backup Sets and CloudBacko Pro Licenses Required** - If you only wish to restore individual files from VM, two separate backup sets are required, one for the VM image and the other for the individual files, and therefore two CloudBacko Pros licenses are required. | | ^ Cons | **No Encryption and Compression** - To ensure optimal restore performance, the backup of the guest VM will **NOT** be encrypted and compressed, therefore, you may have to take this factor in consideration when using this restore method. | **Slower Recovery** - As the entire guest VM has to be restored before you can access any of it’s file(s) or data, the restore time could be long if the guest VM size is large.\\ \\ **Two Backup Sets and CloudBacko Pro Licenses Required** - If you only wish to restore individual files from VM, two separate backup sets are required, one for the VM image and the other for the individual files, and therefore two CloudBacko Pros licenses are required. | | ||

| - | ===== Requirements ===== | ||
| - | <WRAP indent> | ||
| - | ==== Supported Backup Modules ==== | ||
| - | Granular Restore is supported on VMware backup sets created and backed up using CloudBacko Pro installed on a Windows platform with the Granular Restore feature enabled on the backup set. | ||
| - | |||
| - | ==== Backup Quota Storage ==== | ||
| - | As compression is not enabled for Granular backup sets, to optimize restore performance, the storage quota required will be higher than non-Granular backup sets. | ||
| - | |||
| - | ==== Operating System ==== | ||
| - | CloudBacko Pro must be installed on a 64 bit Windows machine as libraries for Granular only supports 64 bit Windows operating system for VMware ESXi/vCenter. CloudBacko Pro must be installed on the following Windows Operating Systems: | ||
| - | | Windows 2008 R2 SP1 or above | Windows 2012 | Windows 2012 R2 | | ||
| - | | Windows 2016 | Windows 7 SP1 or above | Windows 8 | | ||
| - | | Windows 8.1 | Windows 10 | | | ||
| - | |||
| - | ==== Temporary Directory Requirement ==== | ||
| - | Temporary Directory Folder should have at least the same available size as the guest VM to be restored and should be located on a local drive to ensure optimal performance. | ||
| - | |||
| - | ==== Available Spare Drive Letter ==== | ||
| - | One spare drive letter must be available on the Windows machine for the Granular Restore process, as the VDDK virtual disk is mounted on Windows as a logical drive. CloudBacko Pro will automatically take the next available drive letter in alphabetical order for the mounted virtual disk. | ||
| - | |||
| - | <WRAP info>The Windows drive letters A, B, and C are not used by Granular Restore. \\ \\ The Granular Restore assigned drive letter(s) will be released once you exit from AhsayOBM UI.</WRAP> | ||
| - | |||
| - | ==== Network Requirements ==== | ||
| - | Recommended minimum network speed is **at least 100Mbps download speed**. | ||
| - | |||
| - | The network bandwidth requirements will increase in proportion to the size of the guest VM and the incremental delta chain length to ensure optimal performance. Working with limited network bandwidth may severely affect the Granular Restore performance. | ||
| - | |||
| - | You can use an online network speed test website (e.g. [[http://www.speedtest.net]]) to get an idea of the actual bandwidth of the machine. | ||
| - | |||
| - | ==== Other Dependencies ==== | ||
| - | The following dependencies are restore related and therefore they will be checked by AhsayOBM only when Granular Restore is performed. Absence of these elements will not affect the backup job but would cause the restore to fail. | ||
| - | * Microsoft Visual C++ 2015 Redistributable (x86) / (x64) \\ [[https://www.microsoft.com/en-us/download/details.aspx?id=48145]] | ||
| - | |||
| - | * Update for Universal C Runtime in Windows \\ [[https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows]] | ||
| - | |||
| - | * For Windows 7 and Windows Server 2008 R2 only \\ Microsoft Security Advisory 3033929 \\ [[https://docs.microsoft.com/en-us/security-updates/securityadvisories/2015/3033929]] | ||
| - | |||
| - | ==== Permissions ==== | ||
| - | * The Windows login account used for installation and operation of the AhsayOBM client machine requires Administrator privileges. | ||
| - | |||
| - | * For Granular Restore, Windows User Account Control (UAC) must be disabled. | ||
