Users Guide

• Operating system or any data stored on hard disk drives or virtual drives
• vFlash SD card partition information
• Lifecycle log
• Dell diagnostics
• Dell OS Driver Pack
• A Local Key Management (LKM) passphrase, if the LKM-based storage encryption is enabled. However, you
must provide the LKM passphrase after performing the restore operation.
Security
The contents of the backup image file cannot be accessed with any application, even if it is generated without a
passphrase. However, if the backup image file is created using a passphrase, Lifecycle Controller uses the passphrase
to encrypt the backup image file with 128-bit encryption.
Size
On the basis of server configuration, the size of a backup image file can be a maximum of 384 MB.
Performance
• Backup – The time taken to collect the required information and store the backup image file on vFlash SD card is
45 minutes (maximum).
• Restore - The time taken to restore a server using a backup image file depends on the number of components
installed o the server. Most of the server components such as BIOS, NIC, RAID, and other host bus adapters
require multiple system restarts in order to restore the server to its previous configuration. Each restart may
take from one to 15 minutes (for maximum system HW configurations). This restart time is in addition to the time
taken for accessing the backup image file,which is dependent on where it is stored (vFlash SD card, USB flash
drive, or network share).
