HPE2-K45 Exam Dumps : Using HPE SimpliVity

According to the HPE SimpliVity Administration Guide1, the file level restore option allows you to recover individual files or folders from a backup of a virtual machine. Thisoption is useful when you need to restore a specific file that was accidentally deleted or corrupted, without affecting the rest of the virtual machine. The file level restore option supports both Windows and Linux based virtual machines, and can be performed using the HPE SimpliVity plugin in the vSphere Web Client. The file level restore option creates a temporary virtual machine from the backup, mounts the virtual disks, and copies the selected files or folders to a destination of your choice. The temporary virtual machine is then deleted automatically.

The other options are not suitable for recovering a single file from a Linux based virtual machine. Restoring a virtual machine from the backup would overwrite the entire virtual machine with the backup data, which may not be desirable or necessary. Moving a virtual machine from DR site to the primary site would not help if the file was deleted from both sites. Reverting to the SimpliVity snapshot would also overwrite the entire virtual machine with the snapshot data, which may not be the latest or the most relevant version. References:

• HPE SimpliVity 380 Gen10 LFF H and HPE SimpliVity 380 Gen10 SFF H nodes are two types of HPE SimpliVity nodes that differ in their form factor, storage capacity, and performance. LFF stands for large form factor, which means that the node has 3.5-inch hard disk drives (HDDs) and can support up to 40 TB of raw storage capacity. SFF stands for small form factor, which means that the node has 2.5-inch solid state drives (SSDs) and can support up to 23.4 TB of raw storage capacity12.
• HPE SimpliVity nodes can be grouped into clusters, which are logical units of compute and storage resources that share the same configuration and policies. HPE SimpliVity clusters can be further grouped into federations, which are collections of clusters that span across different physical locations and provide unified management and data protection34.
• For this setup, the recommended design is to put SFF and LFF nodes in separate clusters, but within the same federation. According to the HPE SimpliVity Federation Design and Scaling Guide document, the following reasons support this recommendation:

To use this option, you need to select the backup from which you want to restore the files, then click Backup Actions > Restore Files. You will be prompted to enter the following information:

• The name of the virtual machine where you want to restore the files
• The path of the folder where you want to restore the files
• The path of the folder that you want to restore from the backup
• The credentials of the virtual machine where you want to restore the files

After you enter the required information, click OK to start the restore process3.
