If you need to recover data from your Droplet, you can use DigitalOcean’s recovery ISO to regain access and perform recovery operations, like getting access to an interactive shell, running
chrooting into the system.
There are several situations in which you may want to use the recovery ISO:
Your Droplet was disconnected from the network due to an outgoing flood or DDoS. Unusually large amounts of traffic usually indicate that your Droplet was compromised and used to send spam or malicious traffic. In this case, you’ll have received an email from support disabled your Droplet’s normal internet access to protect others from being harmed.
In this case, you can use the recovery ISO to regain access to the Droplet’s filesystem. Then you can put in a support request to enable the Droplet’s network connection so you can recover any files and migrate to a new Droplet.
Your Droplet’s file system is corrupted. File system corruption can happen when software or hardware malfunctions or when your Droplet is abruptly powered off.
The best way to prevent data loss in those situations is with good backups, but you can use the recovery ISO to run
fsck, mount the disk image, or attempt more advanced recovery procedures.
This process involves three steps:
Boot into the recovery ISO from the control panel after powering down the Droplet.
Prepare the Droplet for recovery. For example, if the Droplet has been disconnected from the network, contact support to reconnect it. If the Droplet’s filesystem is corrupted, use the recovery ISO to run
Recover data by migrating files off the Droplet using Filezilla,
scp/SFTP, or other tools and techniques, depending on your situation.
First, power off the Droplet in the safest way available to you. If you have access to the command line, you can use the
sudo poweroff command. If you do not have access to the command line, you can power off the Droplet using the toggle on the Droplet’s page in the control panel.
Once the Droplet is powered off, you can reboot it from the recovery ISO. In the control panel, click Recovery on the left, then click the Boot from Recovery ISO box:
Next, toggle the power button to power your Droplet back on. When it’s on, access the Droplet by clicking on Access to the left, then clicking the Launch Console button. You’ll see a menu like this:
This droplet is booted to the DigitalOcean recovery environment. When you are finished, you may set your Droplet to boot from the local disk again via the DigitalOcean control panel.

The recovery ISO provides a number of options. Which ones you use to prepare the Droplet for recovery depends on the state of the Droplet.
If your Droplet is in a network disconnected state (due to sending an outgoing flood or DDoS, for example), open a support ticket to have it reconnected. The restored network connection allows you to transfer files off of the Droplet. From there, you can use option
1 in the recovery ISO to mount your disk image and gain access to your files.
If you’re trying to recover from file system corruption, you can use option
2 in the recovery ISO to run
fsck, a filesystem check program.
fsck can occasionally cause data corruption on active disks, so only attempt this on an unmounted file system.
fsckas a recovery option can be useful, but it comes with risks and isn’t guaranteed to work, so consider it a last resort method of data recovery. We recommend taking a snapshot of your Droplet first. If the recovery causes data loss, you can restore from the snapshot and try again or use a different method.
After it completes, you have to mount the filesystem into your environment using option
1 in order to access your files. This is because that Linux environment is running from the ISO image, not from the Droplet. Your disk image is detected and mounted under
/mnt in the recovery environment. Then use option
6 to enter the interactive shell and look for recovered files in the
Once your Droplet is prepared, you can offload your files onto a remote machine (like another Droplet or another physical machine). You can use SFTP from the command line or with an SFTP client like Filezilla. Make sure to use the temporary password in the recovery menu when you set up the connection.
~/.ssh/known_hostsfile on your local computer.
You can also
chroot into the filesystem to try more advanced recovery steps. For example, this may allow you to start MySQL so you can attempt to export your databases.
If you were recovering from file system corruption or other problems and the recovery went well, meaning the Droplet itself is salvageable, you can power off from the command line again:
Then, back in the control panel, click Recovery and choose the radio button for Boot from Hard Drive. When you power the Droplet back on, it attempts to boot from its own disk.
