Backing up data while in recovery mode can be an important way to safeguard important files and information in the event of a major system failure or crash. Recovery mode provides access to the hard drive when normal booting is not possible due to software issues or failures. Being able to create a backup from this mode can potentially save data that would otherwise be lost.
What is recovery mode?
Recovery mode is a special startup mode for computers and other devices that provides options for troubleshooting, repairing, restoring or recovering the operating system. It bypasses the normal OS startup process and instead loads a limited operating system directly from a recovery partition or boot disk.
Recovery mode is most commonly accessed by pressing a specific key combination during boot. For example, on Mac computers it is Command + R and on Windows PCs it is typically one of the F keys. This key press interrupts the normal boot sequence and instead loads the recovery tools and options.
Once in recovery mode, users can access certain utilities and functions that can diagnose hardware and software problems, repair startup issues, restore previous backups, reinstall or repair the OS, access data recovery tools, and more. The specific recovery tools available will depend on the device, OS, and manufacturer.
Why back up in recovery mode?
There are a few key reasons why you may want or need to back up your data while booted into recovery mode:
- Normal boot fails: If your computer cannot successfully boot into the operating system normally, recovery mode provides a way to access the hard drive when normal boot is not working.
- System file corruption: An OS system file, registry, or boot sector corruption issue may prevent normal boot, but data may still be accessible from recovery mode.
- OS reinstallation required: If you need to wipe the OS drive and reinstall your operating system from scratch, you’ll want to back up your data first.
- Hard drive issues: With disk errors or a failing drive that may be inaccessible from normal boot, recovery mode can offer a final opportunity to image or back up the drive.
- Encrypted data: Some recovery tools allow backing up encrypted data by utilizing the required decryption keys stored in recovery partitions.
In all these cases, backing up from recovery mode lets you rescue data that you otherwise would not have access to extract normally. It provides a fallback option when normal boot methods fail.
How to access recovery mode
The steps to enter recovery mode depend on your specific operating system and computer/device manufacturer. Here are some common ways to access recovery mode:
Windows
- Hold Shift and click Restart from the start menu or Settings app. This boots to the recovery options.
- Repeatedly press F8 during boot up to access the Advanced Boot Options menu, then select Repair Your Computer.
- Press F11 during boot to load Dell recovery tools or F9 for HP recovery.
- Insert the Windows installation media and boot from it, then choose Repair instead of Install.
Mac
- Hold Command + R while booting to load Apple’s recovery HD partition.
- Hold Option + Command + R to boot to internet recovery over a network connection.
- Hold Shift + Option + Command + R for Apple Diagnostics.
- Hold D while booting from installation media to access utilities.
Linux
- Press Esc during boot to access the GRUB boot loader menu, then select the recovery mode option.
- Hold Shift during boot to access the GRUB menu, then choose recovery mode.
- Press e in GRUB to edit the kernel parameters, add “single” to boot to single-user recovery mode.
Refer to your operating system or computer/device documentation for the exact keys to access recovery mode.
Backing up from recovery mode
Once you are booted into recovery mode, there are different options available for backing up your data depending on the specific recovery tools and utilities included.
Using backup software
Some recovery modes will allow you to launch certain system backup or imaging software to create backups. For example, Windows includes the System Image Backup tool that can be accessed from recovery mode to create full disk images or backups of partitions or folders.
Third-party backup tools like Macrium Reflect, Veeam, and Clonezilla may also be accessible from recovery mode. Check your software documentation on whether emergency backups from recovery mode are supported.
Copy files to external media
You can directly copy important files and folders off to external devices from the recovery interface. This lets you manually pull data off the drive to an external hard drive, USB flash drive, or other removable media. Use file explorer or utility tools provided in the recovery environment to copy the files.
Network backups
Some recovery modes provide access to wired networks and let you backup or transfer files over the network to a shared drive or cloud storage service. This allows backups direct to network locations in the absence of internet access.
Cloud storage syncing
For recovery modes that do provide internet access, you may be able to utilize cloud backup services to sync files offsite. Applications like OneDrive, Dropbox, and iCloud could have data uploaded, depending on what utilities are available.
Drive cloning
Creating a clone or disk image of the drive from recovery mode will fully backup all data and partitions. Tools like dd or Clonezilla can be used to create an image file that can be stored on external media.
Terminal access
Recovery modes for Linux or Mac provide terminal access that can allow advanced data backup solutions using command line tools like rsync, scp, and dd to copy, sync, or clone data to different storage locations.
