Commit Revisions and Archival
Back to Top
Instead of manually backing up and maintaining backup files, EdgeOS also supports an automatic remote backup feature. The commit-archive command allows you to automatically backup the configuration after each commit.
CLI: Access the Command Line Interface. You can do this using the CLI button in the GUI or by using a program such as PuTTY.
1. Enter configuration mode.
ubnt@edgerouter:~$ configure
2. Automatically send committed configurations to a TFTP, SCP or FTP server:
[edit]
ubnt@edgerouter# set system config-management commit-archive location ?
Possible completions:
Detailed information:
“scp://
“ftp://
“tftp://
[edit]
ubnt@edgerouter# set system config-management commit-archive location tftp://192.168.1.1/archive
3. Commit the changes.
[edit]
ubnt@edgerouter# commit
Archiving config… tftp://192.168.1.1/archive OK
You can also keep a specified number of commit revisions (configuration files) on the local device by using the commit‑revisions statement.
1. Enter configuration mode.
ubnt@edgerouter:~$ configure
2. Specify the amount of revisions to keep.
[edit]
ubnt@edgerouter# set system config-management commit-revisions 10
3. Commit the changes.
[edit]
ubnt@edgerouter# commit
4. Test the feature by enabling a random service.
[edit]
ubnt@edgerouter# set service telnet port 23
ubnt@edgerouter# compare
[edit service]
+telnet {
+ port 23
+}
[edit]
ubnt@edgerouter# commit
[ service telnet ]
Starting the telnet service. Check /var/log/messages.
5. Verify the commit revision list.
ubnt@edgerouter:~$ show system commit
0 2018-04-02 22:07:58 by ubnt via cli
commit
1 2018-04-02 22:07:50 by ubnt via cli
commit
2 2018-04-02 22:07:50 by root via init
commit
NOTE: The currently active configuration is commit revision 0.
The following commands allow you to compare the different commit files.
show system commit List all the current commit revisions
show system commit diff
show system commit file
It is possible to add comments to commits to easily see which revision added which feature:
[edit]
ubnt@edgerouter# delete service telnet
[edit]
ubnt@edgerouter# commit comment removed-telnet
[edit]
ubnt@edgerouter# run show system commit
0 2018-04-02 22:18:07 by ubnt via cli
removed-telnet
1 2018-04-02 22:17:17 by ubnt via cli
commit
2 2018-04-02 22:17:08 by ubnt via cli
commit
Lastly, you can restore a previous configuration revision by using the rollback command.
[edit]
ubnt@edgerouter# rollback ?
Possible completions:
Revisions:
0 2018-04-02 22:18:07 ubnt by cli
1 2018-04-02 22:17:17 ubnt by cli
2 2018-04-02 22:17:08 ubnt by cli
3 2018-04-02 22:07:58 ubnt by cli
4 2018-04-02 22:07:50 ubnt by cli
5 2018-04-02 22:07:50 root by init
