Backup and Import to a New Environment¶

The steps below show how to backup and import to a new environment.

Export:

On the source system, create a remote backup location, for example location name sftpbackup:

backup add sftpbackup <URI>

For example:
```
backup add sftpbackup sftp://sftpusr:[email protected]/home/sftp
```
If a directory is specified in the <URI>, this will be created during the backup. Backups to sftp require ssh key-based authentication to be set up. Refer to SSH key management for further details.

Alternatively, enter the password at the prompt, for example:
```
$ backup add sftpbackup sftp://sftpusr:[email protected]/home/sftp

 No password found. Do you want to use sshkeys? no
 What is the host ssh password?

 <type password here>

 Location has been added
```
Create a local backup:

Important

Backups should be created and restored in a screen session - see: Using the screen command.

backup create localbackup

In a multi-node configuration, the database backup will be created on the secondary node with the highest priority. Use database config to check the priority.

List backups to get the date:

backup list

For example:

$ backup list
 localbackup:
    URI: file:///backups
    Backups:
       1 backups have been created - most recently 2020-03-19 08:21
 sftpbackup:
    URI: sftp://sftpusr:********@172.29.41.107:home/sftp
    Backups:
       No backups created yet

Export the local backup to the remote destination created by backup add <remote_name>.

The system ID is appended as a directory to the backup <URI> destination path. This can be checked locally by running system id.
The backup file is called <hostname>_<timestamp>.tar.gz.

Example output:

platform@VOSS:~$ backup export localbackup sftpbackup 2020-04-02 11:34
This operation could take a while if the backup is sizeable. Do you wish to continue? y

Import:

Note

For large backup files that cannot be imported due to space limitations, see: Restoring backup files too large for import.
1. From the SFTP server, scp the VOSS_202004021348.tar.gz file to the new box (for example, platform@172.29.21.97). If the file on the SFTP server is in the directory /backups/49940d3feaa39a6a9f36cb5ff533202157c3b77a, change to the directory, then:
```
$ ls

 VOSS_202004021348.tar.gz

$ scp VOSS_202004021348.tar.gz [email protected]:/opt/platform/admin/home/media/
```
2. Import the file as a local backup, for example:
```
$ backup import localbackup media/VOSS_202004021348.tar.gz
```
3. Get the file timestamp of the imported backup with backup list and restore the backup, for example:

  Backups should be created and restored in a screen session - see: Using the screen command.
```
$  backup restore localbackup 2020-04-02 15:41
```

Restoring backup files too large for import¶

If a backup file is available and is too large to copy into the local system /home/media/ directory, the following procedure can be followed. (Available space on home/media can be checked using diag disk.)

On the system where the backup is to be restored, add the remote SFTP site, for example:
```
backup add sftpbackup sftp://sftpusr:[email protected]/home/sftp
```
Obtain the system UUID by running system id. It should look like this:
```
49940d3feaa39a6a9f36cb5ff533202157c3b77a
```
Given an available backup file, e.g. VOSS_202004021348.tar.gz, (with timestamp reference: 2020-04-02 15:41) this file can be extracted to the remote SFTP site configured above as follows:
1. On the remote SFTP site, locate the sub-directory with the name of the UUID, for example
```
/home/sftp/49940d3feaa39a6a9f36cb5ff533202157c3b77a
```
2. Extract the backup file in this directory. Ensure that the extracted backup files are listed in the root of this directory (not all in a subdirectory).
On the system where the backup is to be restored, run the remote restore, for example:
```
$  backup restore sftpbackup 2020-04-02 15:41
```
