• 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 le cannot be accessed with any application, even if it is generated without a passphrase.
However, if the backup image le is created using a passphrase, Lifecycle Controller uses the passphrase to encrypt the backup
image le with 128-bit encryption.
Size
On the basis of server conguration, the size of a backup image le can be a maximum of 384 MB.
Performance
• Backup – The time taken to collect the required information and store the backup image le on vFlash SD card is 45 minutes
(maximum).
• Restore - The time taken to restore a server using a backup image le 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 conguration. Each restart may take from 1–15 minutes (for maximum system
hardware congurations). This restart time is in addition to the time taken for accessing the backup image le, which is
dependent on where it is stored (vFlash SD card, USB drive, or network share).
Supported Components
