Using Junos OS to Configure a Router or Switch to Transfer Its Configuration to an Archive Site

You can configure a router or switch to transfer its configuration to an archive file periodically. The following tasks describe how to transfer the configuration to an archive site:

1. Configuring the Router or Switch to Transfer Its Currently Active Configuration to an Archive
2. Configuring the Transfer Interval for Periodic Transfer of the Active Configuration to an Archive Site
3. Configuring Transfer of the Current Active Configuration When a Configuration Is Committed
4. Configuring Archive Sites for Transfer of Active Configuration Files

Configuring the Router or Switch to Transfer Its Currently Active Configuration to an Archive

If you want to back up your device’s current configuration to an archive site, you can configure the router or switch to transfer its currently active configuration by FTP or secure copy (SCP) periodically or after each commit.

To configure the router or switch to transfer its currently active configuration to an archive site, include statements at the [edit system archival configuration] hierarchy level:

Note: When specifying a URL in a Junos OS statement using an IPv6 host address, you must enclose the entire URL in quotation marks ("") and enclose the IPv6 host address in brackets ([ ]). For example, “ftp://username<:password>@[ipv6-host-address]<:port>/url-path”

Configuring the Transfer Interval for Periodic Transfer of the Active Configuration to an Archive Site

To configure the router or switch to periodically transfer its currently active configuration to an archive site, include the transfer-interval statement at the [edit system archival configuration] hierarchy level:

The interval is a period of time ranging from 15 through 2880 minutes.

Configuring Transfer of the Current Active Configuration When a Configuration Is Committed

To configure the router or switch to transfer its currently active configuration to an archive site each time you commit a candidate configuration, include the transfer-on-commit statement at the [edit system archival configuration] hierarchy level:

Note: When specifying a URL in a Junos OS statement using an IPv6 host address, you must enclose the entire URL in quotation marks ("") and enclose the IPv6 host address in brackets ([ ]). For example, “scp://username<:password>@[ipv6-host-address]<:port>/url-path”

Configuring Archive Sites for Transfer of Active Configuration Files

When you configure the router or switch to transfer its configuration files, you specify an archive site to which the files are transferred. If you specify more than one archive site, the router or switch attempts to transfer files to the first archive site in the list, moving to the next site only if the transfer fails.

When you use the archive-sites statement, you can specify a destination as an FTP URL, or SCP-style remote file specification. The URL type file:// is also supported.

To configure the archive site, include the archive-sites statement at the [edit system archival configuration] hierarchy level:

Note: When specifying a URL in a Junos OS statement using an IPv6 host address, you must enclose the entire URL in quotation marks ("") and enclose the IPv6 host address in brackets ([ ]). For example, “scp://username<:password>@[ipv6-host-address]<:port>/url-path”

When you specify the archive site, do not add a forward slash (/) to the end of the URL.

The destination filename is saved in the following format, where n corresponds to the number of the compressed configuration rollback file that has been archived:

Note: The time included in the destination filename is always in Coordinated Universal Time (UTC) regardless of whether the time on the router is configured as UTC or the local time zone. The default time zone on the router or switch is UTC.
