||
### How To Backup Installed Packages Using apt-clone?
|
||
|
||
Once you have successfully installed the apt-clone package. Simply give a location where do you want to save the backup file.
|
||
|
||
We are going to save the installed packages backup under `/backup` directory.
|
||
|
||
The apt-clone utility will save the installed packages list into `apt-clone-state-Ubuntu18.2daygeek.com.tar.gz` file.
|
||
|
||
```
|
||
$ sudo apt-clone clone /backup
|
||
```
|
||
|
||
We can check the same by running the ls Command.
|
||
|
||
```
|
||
$ ls -lh /backup/
|
||
total 32K
|
||
-rw-r--r-- 1 root root 29K Apr 20 19:06 apt-clone-state-Ubuntu18.2daygeek.com.tar.gz
|
||
```
|
||
|
||
Run the following command to view the details of the backup file.
|
||
|
||
```
|
||
$ apt-clone info /backup/apt-clone-state-Ubuntu18.2daygeek.com.tar.gz
|
||
Hostname: Ubuntu18.2daygeek.com
|
||
Arch: amd64
|
||
Distro: bionic
|
||
Meta: libunity-scopes-json-def-desktop, ubuntu-desktop
|
||
Installed: 1792 pkgs (194 automatic)
|
||
Date: Sat Apr 20 19:06:43 2019
|
||
```
|
||
|
||
As per the above output, totally we have 1792 packages in the backup file.
|
||
|
||
### How To Restore The Backup Which Was Taken Using apt-clone?
|
||
|
||
You can use any of the remote copy utility to copy the files on remote server.
|
||
|
||
```
|
||
$ scp /backup/apt-clone-state-ubunt-18-04.tar.gz Destination-Server:/opt
|
||
```
|
||
|
||
Once you copy the file then perform the restore using apt-clone utility.
|
||
|
||
Run the following command to restore it.
|
||
|
||
```
|
||
$ sudo apt-clone restore /opt/apt-clone-state-Ubuntu18.2daygeek.com.tar.gz
|
||
```
|
||
|
||
Make a note, The restore will override your existing `/etc/apt/sources.list` and will install/remove packages. So be careful.
|
||
|
||
If you want to restore all the packages into a folder instead of actual restore, you can do it by using the following command.
|
||
|
||
```
|
||
$ sudo apt-clone restore /opt/apt-clone-state-Ubuntu18.2daygeek.com.tar.gz --destination /opt/oldubuntu
|
||
```
