- Unmount the SD card and insert the card which you want to make a clone for your Raspberry Pi data. Again, make sure for the unmount partition on the memory device; Go to the terminal and write the below command sudo dd if=/raspberryclone.dmg of=/dev/disk. Wait till the writing process is finished and then remove the card from the system.
Use the following command to use the dd utility to backup your Raspberry Pi SD card, changing /dev/disk1 to your disk's name and path: sudo dd if=/dev/disk1 of=/PiSDCardBackup.dmg Enter your password when prompted. This will create a file named PiSDCardBackup.dmg in the user directory. Here, we'll guide you through some backup techniques for your Raspberry Pi system. Home folder A sensible way to keep your home folder backed up is to use the tar command to make a snapshot archive of the folder, and keep a copy of it on your home PC or in cloud storage.
It is highly recommended that you keep regular backups of any important files. Backups are often not limited to user files; they could include configuration files, databases, installed software, settings, and even an entire snapshot of a system.
Here, we'll guide you through some backup techniques for your Raspberry Pi system.

Home folder
A sensible way to keep your home folder backed up is to use the
tar
command to make a snapshot archive of the folder, and keep a copy of it on your home PC or in cloud storage. To do this, enter the following commands:This creates a tar archive called
pi_home.tar.gz
in /home/
. You should copy this file to a USB stick or transfer it to another machine on your network.MySQL
If you have MySQL databases running on your Raspberry Pi, it would be wise to keep them backed up too. To back up a single database, use the
mysqldump
command:This command will back up the
recipes
database to the file recipes.sql
. Note that, in this case, no username and password have been supplied to the mysqldump
command. If you don't have your MySQL credentials in a .my.cnf
configuration file in your home folder, then supply the username and password with flags:To restore a MySQL database from a dumpfile, pipe the dumpfile into the
mysql
command. Provide credentials, if necessary, and the database name. Note that the database must exist, so create it first:Alternatively, you can use the
pv
command to see a progress meter as the dumpfile is processed by MySQL. This is not installed by default, so install with sudo apt install pv
. This command is useful for large files:SD card image
It may be sensible for you to keep a copy of the entire SD card image, so you can restore the card if you lose it or it becomes corrupt. You can do this using the same method you'd use to write an image to a new card, but in reverse.
In Linux:
This will create an image file on your computer which you can use to write to another SD card, and keep exactly the same contents and settings. To restore or clone to another card, use
dd
in reverse:How To Make A Dmg Raspberry Backup Mac
These files can be very large, and compress well. To compress, you can pipe the output of
dd
to gzip
to get a compressed file that is significantly smaller than the original size:To restore, pipe the output of
gunzip
to dd
:If you are using a Mac, the commands used are almost exactly the same, but
4M
in the above examples should be replaced with 4m
, with a lower case letter.See more about installing SD card images.

You could write a Bash script to perform each of these processes automatically, and even have it performed periodically using cron.
