A\u00a0feature request<\/a>\u00a0for\u00a0tarbackup<\/a>\u00a0is using a private ssh key instead of a password to connect to the tarbackup server when using sftp to backup files. I’m happy to report that we now support public\/private keys for sftp authentication!<\/p>\n

To use an ssh key with tarbackup, first use this command to create your public\/private key-pair:
\n
\n# mkdir ~\/.ssh
\n# cd ~\/.ssh
\n# ssh-keygen -f tarbackup_rsa -C .youremail. -N . -t rsa -q
\n<\/code><\/p>\n

This will generate 2 files: tarbackup_rsa and tarbackup_rsa.pub. tarbackup_rsa is your private ssh key, you will keep this on your computer as proof that you are who you are. tarbackup_rsa.pub is a public key that you\u00a0send to the server<\/a>\u00a0so that tarbackup.com can authenticate you when you log in via sftp in the future.<\/p>\n

To use your private key to authenticate you when you login via sftp, you need to create an ssh_config file in your home directory with:
\n
\n# echo \"IdentityFile ~\/.ssh\/tarbackup_rsa\" > ~\/ssh_config
\n<\/code>
\nThis is the config file that specifies where your private ssh key is.<\/p>\n

You’ll pass the ssh_config file as a parameter to the sftp program when you connect to tarbackup.com via sftp:
\n
\n# sftp -F ~\/ssh_config account@tarbackup.com
\n<\/code>
\n <\/p>\n

And that’s it! Let me know if you have any feedback or questions@davidnanch<\/a>.<\/p>\n
