274 Chapter 11 Backing Up and Restoring BCM50 Data
NN40020-600NN40020-600
For USB storage devices, an additional copy of the backup archive is stored in the file backup.tar;
the BCM will reference this file during a USB restore operation. Only the most recent backup to
the USB storage device is available for a restore operation. To access historical backup archives,
attach the USB storage device to a personal computer and use the Restore from My Computer
option.

Backup destinations

Table 72 lists the destinations to which you can back up configuration and application data.
Whichever destination you choose, the backup operation replaces the BCM’s own copy of the
archive, so that a copy of the most recent backup always remains on the BCM50. You can use this
to restore your BCM50 without transferring a backup from an external device or server.
Table 72 Backup destinations
Destination Description
BCM50 For an immediate backup, saves backup archives to the hard drive of the
BCM50.
You cannot specify a path. Each backup rewrites any pre-existing backup
of the same type.
My Computer For an immediate backup, saves backup archives to any accessible
location on the client PC on which the BCM50 Element Manager is
installed. You can specify a name for the backup, so that the pre-existing
backup is not automatically overwritten.
Network Folder Saves data to a shared network folder.
The remote server must provide a Microsoft Windows-like shared file
resource and a user account with rights to create and write files in the
destination location. You cannot browse the network directories to select
the destination folder, but you can specify a directory by identifying the
path.
USB Storage Device Saves backup archives to a USB storage device.
The files will be written to the top directory level. You cannot specify a path
to a different directory on the storage device. Each backup overwrites any
pre-existing backup of the same type.
A USB storage device must be formatted as FAT32.
FTP Server Saves backup archives to a File Transfer Protocol server.
Credentials and backup data are sent without encryption. The remote
server must provide an FTP server application and a user account with
rights to allow the BCM50 to create and write files in the destination
location.
You cannot browse the FTP server to select the destination folder, but you
can specify a directory by identifying the path.
SFTP Server Saves backup archives to an SFTP server. This method encrypts the login
credentials and the data in transit.
You must set up the remote SFTP server to allow the BCM50 to
communicate with the SFTP server. The BCM50 system can generate an
SSH pubiic key, which you must install on the remote SFTP server. For
information about SSH keys, see the chapter BCM50 Security.
