Users Guide

• Signature to validate that the backup file is not tampered and generated by Lifecycle Controller.
The server profile backup image file does not contain:
• 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
Based on the server configuration, the size of a backup image file can be a maximum of 384 MB.
Performance
• Back up — The time taken to collect the required information and store the backup image file on a 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 on 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 1–15 minutes (for maximum system hardware
configurations). This restart time is in addition to the time taken for accessing the backup image file, which depends on where it is
stored (vFlash SD card, USB drive, or network share).
