Install Rsync
ataker@htb[/htb]$ sudo apt install rsync -yRsync - Backup a local Directory to our Backup-Server
ataker@htb[/htb]$ rsync -av /path/to/mydirectory user@backup_server:/path/to/backup/directoryThis command will copy the entire directory (/path/to/mydirectory) to a remote host (backup_server), to the directory /path/to/backup/directory. The option archive (-a) is used to preserve the original file attributes, such as permissions, timestamps, etc., and using the verbose (-v) option provides a detailed output of the progress of the rsync operation.
We can also add additional options to customize the backup process, such as using compression and incremental backups. Also, we can backup the destination folder before synchronization, this way, if something goes wrong during backup, we will have access to old files in destination. We can do this like the following:
ataker@htb[/htb]$ rsync -avz --backup --backup-dir=/path/to/backup/folder --delete /path/to/mydirectory user@backup_server:/path/to/backup/directoryWith this, we back up the mydirectory to the remote backup_server, preserving the original file attributes, timestamps, and permissions, and enabled compression (-z) for faster transfers. The --backup option creates incremental backups in the directory /path/to/backup/folder, and the --delete option removes files from the remote host that is no longer present in the source directory.
If we want to restore our directory from our backup server to our local directory, we can use the following command:
Rsync - Restore our Backup
Rsync - Restore our Backup
ataker@htb[/htb]$ rsync -av user@remote_host:/path/to/backup/directory /path/to/mydirectoryEncrypted Rsync
To ensure the security of our rsync file transfer between our local host and our backup server, we can combine the use of SSH and other security measures. By using SSH, we are able to encrypt our data as it is being transferred, making it much more difficult for any unauthorized individual to access it. Additionally, we can also use firewalls and other security protocols to ensure that our data is kept safe and secure during the transfer. By taking these steps, we can be confident that our data is protected and our file transfer is secure. Therefore we tell rsync to use SSH like the following:

Secure Transfer of our Backup
ataker@htb[/htb]$ rsync -avz -e ssh /path/to/mydirectory user@backup_server:/path/to/backup/directory
