rsync --rsync-path 'sudo rsync' username@source:/folder/ /local/

Rsync remote data as root using sudo

If your user has sudo on the remote box, you can rsync data as root without needing to login as root. This is very helpful if the remote box does not allow root to login over SSH (which is a common security restriction).

  • connect to a remote server using ftp protocol over FUSE file system, then rsync the remote folder to a local one and then unmount the remote ftp server (FUSE FS) it can be divided to 3 different commands and you should have curlftpfs and rsync installed

  • Clone a root partition. The reason for double-mounting the root device is to avoid any filesystem overlay issues. This is particularly important for /dev. Also, note the importance of the trailing slashes on the paths when using rsync (search the man page for "slash" for more details). rsync and bash add several subtle nuances to path handling; using trailing slashes will effectively mean "clone this directory", even when run multiple times. For example: run once to get an initial copy, and then run again in single user mode just before rebooting into the new disk. Using file globs (which miss dot-files) or leaving off the trailing slash with rsync (which will create /mnt/target/root) are traps that are easy to fall into.

  • rsync by itself doesn't support copying between two remote hosts, but if you use sshfs you can pretend one of them is local. If you have a passphrase-less ssh-key, you can even put this script into a cron job. A faster alternative is to run ssh-keygen on remote1 and put the pubkey into remote2:~/.ssh/authorized_keys, running rsync on remote1 (or vice versa), but the problem with that is that now a hacker on remote1 can access remote2 at any time. The above method ensures your local computer stays the weak link. Show Sample Output


    -1
    mkdir r1 && sshfs remote1:/home/user r1 && rsync r1/stuff remote2:~/backups/

  • Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)
