In the Application-aware mode, NAKIVO Backup & Replication triggers custom scripts you provide prior to making snapshots of LVM volumes.
If you run a VM with Linux or FreeBSD guest OS under Hyper-V, refer Hyper-V support article about supported Linux and FreeBSD versions.
To make application-aware mode working on Linux guest OS, you need to put custom scripts called
/usr/sbin directory and give them executive permissions. When the backup job starts running, NAKIVO Backup & Replication triggers these scripts.
thaw scripts require root permissions to be executed.
When a non-root user is used, scripts invocation will be done via
sudo, therefore the following requirements must be met.
1. Provided credentials must have full access without a password in
2. Provided credentials must be allowed to execute freeze/thaw scripts without a password in
3. If NAKIVO Backup & Replication logs into Amazon EC2 instance and there's no password for Linux user, provided credentials must have a password to execute sudo:
- Log into the instance via SSH client using pem key
sudo passwd ubuntu
/etc/sudoersin a text editor
ubuntu ALL=(ALL) NOPASSWD:ALLto the bottom of the file
/etc/ssh/sshd_configin a text editor
set up PasswordAuthentication yes
- Reboot the instance
- Log into the instance via SSH client without pem key, enter password
