Azure SFTP Gateway Backup and Recovery
Note: This page applies to SFTP Gateway version 2.x. Visit Here for documentation on version 3.x.
We have developed the following process for recovering SFTP Gateway users and configurations. This will be useful in the following cases:
- A region outage requires you to do a cold failover to another region
- You need to migrate or replicate to another region
- An SFTP Gateway instance is accidentally deleted
Note: The backup and recovery process captures the credentials for both password and SSH key based authentication.
Make sure you test this process thoroughly in your own environment.
Disclaimer: This backup and recovery strategy is intended for standard installations of SFTP Gateway. If you have customized your SFTP Gateway installation(s), please contact us at firstname.lastname@example.org to see if this solution will work for you.
Creating a backup
The SFTP Gateway backup script is a Python script that you install on your SFTP Gateway instance. The script backs up
the following data to a single flat YAML file (and later gets compressed as a
- user properties
- user passwords/keys
- global SFTP Gateway properties
This backup artifact can be imported into a new SFTP Gateway stack to restore settings and configuration.
backup.py script will create a backup file named
sftpgw-backup-YYYY-MM-DD-HH-MM-SS.tar.gz. By default,
this file is saved in the
/opt/sftpgw/backups directory (which gets created if it doesn't already exist).
Run a backup script to generate an artifact
SSH to the
2.001.xserver as the administrator user (e.g.
Download the backup script
cd /home/centos/ wget http://www.sftpgateway.com/backup-and-recovery/backup.py
Run the backup script
sudo su python backup.py
Locate the backup artifact
cd /opt/sftpgw/backups/ ls -la
Look for a backup file in the format
This will later be used to recover SFTP Gateway users and configuration.
Move this backup artifact to your home directory
cp -a /opt/sftpgw/backups/sftpgw-*.tar.gz /home/centos/
In a different terminal session, copy this file to your local machine
scp -i <private-key> centos@<ip-address>:/home/centos/sftpgw-*.tar.gz .
Transfer this artifact to the new VM and run a script to restore settings from the artifact
To import SFTP Gateway users and configuration:
Upload the backup artifact to the new server
scp -i <private-key> sftpgw-*.tar.gz centos@<ip-address>:/home/centos/
SSH to the server as the administrator user
ssh -i <private-key> centos@<ip-address>
Download the recovery script:
Run the python recovery script
sudo python recovery.py sftpgw-YYYY-MM-DD-HH-MM-SS.tar.gz
If have the web admin UI open, make sure you hard-refresh the web browser to see the latest changes.
Your new instance will be in the same state as the original instance, including your users and SFTP Gateway configuration.
