### Backup IBM Aspera HTTP Gateway Directory (Bash)

Source: https://www.ibm.com/docs/en/aspera-http-gateway/2.3_topic=upgrade-upgrading-http-gateway

This command creates a backup of the current httpgateway directory before upgrading. It ensures that critical configuration files and data are preserved in case of any issues during the upgrade process. The `-P` flag ensures parent directories are created if they don't exist, and `cp -rivp` performs a recursive, interactive, verbose copy, preserving permissions and timestamps.

```bash
mkdir -P /root/httpgateway-2-3-0.bkup
cp -rivp /opt/aspera/httpgateway /root/httpgateway-2-3-0.bkup

```bash
# usermod -aG wheel httpgateway
```

--------------------------------

### Backup HTTP Gateway Configuration (Shell)

Source: https://www.ibm.com/docs/en/aspera-http-gateway/2_topic=appendix-non-root-user-processes
