AMF backups
AMF backups are an essential part of AMF network operation, as they are the mechanism by
which AMF master nodes update their records of the AMF network. By default, AMF master
nodes are configured to perform automatic scheduled backups of the entire AMF network
once per day at 3.00am. AMF backups are stored on external removable media (e.g. USB
Flash stick, SD card), thus it is a requirement that all AMF masters have external removable
media installed that is of sufficient capacity to hold all of the relevant files stored in the Flash
by every node in the AMF network.
Typi c al ly a 4GB capacity external media device would be of sufficient size to hold backups for
a 40 node AMF network.
The AMF node backup system has been designed such that the external media used to store
the backup data can still be used to store other data, however care needs to be taken to
ensure that enough space is reserved for future AMF backups.
AMF requires up to 128MB backup space for SBx8100 nodes and up to 64MB backup
space for other nodes. The show atmf backup command output will provide warnings
if capacity on the backup media falls below a safe level.
Here is some example output of the show atmf backup command showing a backup
media space warning:
