Backup PVE using PBS

[Tacioandrade]

Don't worry, the languages really are similar. ;-) I have to apologize for accidentally posting in Portuguese in an English forum. haha

About the backup I do the following based on the script created by a friend of the Telegram group "Proxmox Backup Server: Brasil"

#!/bin/bash

# strings to identify host,datestamp and pbs creds
export PBS_REPOSITORY=usergranular@pbs@10.10.10.1:datastore
export PBS_PASSWORD=myverysecretpassword

proxmox-backup-client login --repository $PBS_REPOSITORY
proxmox-backup-client backup configs.pxar:/srv/ --repository $PBS_REPOSITORY --backup-id $HOSTNAME

## unset the PBS_x variables after backup
unset PBS_REPOSITORY
unset PBS_PASSWORD
exit 0

Just be careful not to use the PBS root credentials, instead use a credential that only allows the backup to be performed, that way your backup is safe in case of server attacks!

Its even better to create a token instead of a user. Then you can set the rights that the token is allowed to do and what not and use the token for login.

Really! In this case I do it per user because that's how I know how to use it, with token I thought it would only work for API integration or something.

Its works fine with the PBS client. You just use the Token instead of the user and the token secret instead of the password.

Thanks for sharing Tacioandrade!

Great suggestion to use the Token login method Dunuin.
