Backing Up Data in Rescue Mode
If your server's operating system will not boot, you can use the Linux Rescue System to access your files and back them up to a safe, external location. The most powerful tool for this is rsync, which can efficiently copy large amounts of data over the network.
Prerequisites:
- Your server booted into the Linux Rescue System. → How to Start Rescue Mode
- A second, functioning server or storage location (the "backup destination") that is accessible via SSH from the rescue environment.
Step-by-Step Guide
First, you need to mount the hard drive of your broken server to make the files accessible.
- Log into the rescue environment via SSH.
- Identify your main partition using
lsblk(e.g.,/dev/sda3). - Mount the partition to the
/mntdirectory.
Mount Filesystem
# Replace /dev/sda3 with your actual partition
mount /dev/sda3 /mnt
Your server's files are now accessible under the /mnt directory.
