A configuration backup does include:
Metadata associated with the system as a whole, such as settings for NTP, NIS, LDAP, and other services.
Network device, datalink, and interface configuration.
User accounts, roles and privileges, preferences, and encrypted passwords for local users (not directory users).
Alerts and thresholds and their associated rules.
iSCSI targets and initiators.
iSCSI service properties.
SRP targets and initiators.
Encryption configuration: All contents of the LOCAL keystore, including the keys (stored in an encrypted form). Configuration details, including the Registration PIN for OKM and the names only of the keys.
A configuration backup does not include:
User data (shares and LUNs). Your user data must be backed up separately, using NDMP backup software, snapshots, and/or remote replication.
User passwords for directory users. These remain stored solely in your separate network directory service, such as LDAP or Active Directory, and are not stored in the backup or restored.
Metadata directly associated with user data, such as snapshot schedules, user quotas, compression settings, and other attributes of shares and LUNs.
Analytics and logs. Events can be redirected to external SNMP trap receivers or e-mail destinations using Alerts rules.
System software. The system software is automatically backed up as part of the System Update capability.
Replication targets.
