Recovering lost files or formatted disks in a cloud server can be a daunting task, especially if you're not familiar with the recovery process. Unlike physical computers, where you can simply remove the disk and attempt to recover the data, cloud servers require a more complicated approach.

Gracefully shut down the system. This will prevent any further damage to the disk and improve the chances of recovering lost data.
Mount the formatted disk as read-only. It is essential to mount the formatted disk as read-only or avoid any read operations to the disk if possible.

Select "Quick Search" to search for lost partitions.
If Quick Search doesn't find the lost partition, select "Deeper Search" to search for more partitions.
Select the lost partition and choose "Write" to save the partition table.

Recovering lost files from boot partitions from the cloud server

Use the dd command to transfer the data from a deleted instance to a newly created disk in a new server, you can use the dd command.
- Use the following command to copy the data from the deleted disk block to a new disk for storing the block:
# Cloning boot disk remotely # run this command from server where file was deleted sudo dd if=/dev/sdX | ssh username@server sudo dd of=/dev/sdY
Replace "sdX" with the deleted disk block and "sdY" with a new disk for storing the block.
Use any tools mentioned above to start recovery.
Follow the Instructions Carefully While the recovery process begins, it can be time-consuming, so be patient.
