2. Download the backup .MD5 (Checksum) File

curl --noproxy <controller_ip> --header "X-Auth-Token:<auth_token>" --fail -ksSfL --

request GET --url

"https://<controller_ip>:8443/sdn/v2.0/systems/<controller_uid>/backup?csum=true" >

<path-and-file-name>.zip.MD5

Note

The path-and-file-name string should be identical for the .zip and the .MD5

files in a given backup file pair.

Recommended Backup Practices

 Do not run backup while making configuration changes. Instead, run the backup

after completing configuration changes. Otherwise, an inconsistent system state

could result with a subsequent restore.

 Always back up all of the controllers in a team after a configuration change. Just

backing up a subset of the controllers is not sufficient.

 Back up all of controllers in a team at approximately the same time. (Team backups

can be in sequence or in parallel). Do not allow days to pass in-between backups of

different controllers in the same team.

 A completed backup should be downloaded from the controller to another location

for safekeeping. Include the IP address in the backup filename, so you can easily

determine which backup belongs to which controller in a team. Recommended file

naming is:

o sdn_controller_backup_<ip-address>.zip

o sdn_controller_backup_<ip-address>.zip.MD5

 Store the backups and associated checksum (MD5) files you take of each controller

in the team together, so they can easily be retrieved for a future restore.

Notes

If any controller in a team fails to complete the backup, start the backup over

for all members of the controller team.

Examples of cURL commands in this guide use the "--noproxy" option, which

is appropriate where execution of cURL commands do not need a proxy to

access controllers. If your network is set up such that a proxy is needed to

access controllers, use the "--proxy" option. For details on cURL proxy

options, visit http://curl.haxx.se/docs/manpage.html .
