System identification information such as model number and Service
Tag. For example, R720 and 1P3HRBS.
Date and time the backup was last taken.
Currently installed hardware inventory information.
Firmware for each component.
Encrypted
Component configuration information.
User name and password for RAID controller and BIOS.
Component certificates.
Licenses.
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).
