Creazione snapshot

  • Impostare
backup-pre
in modo che crei uno snapshot del sistema montato su /media/backup con tutti i fs da backuppare.


Installazione client

Debian 11 Bullseye

* TODO

Debian 10 Buster

ATTENZIONE: install la versione 1.14 che non supporta namespace 

sudo  wget http://download.proxmox.com/debian/proxmox-ve-release-6.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-6.x.gpg

vi /etc/apt/sources.list.d/pbs-client.list

deb http://download.proxmox.com/debian/pbs-client buster main

apt update

apt install proxmox-backup-client

Installazione script di backup

Con pacchetto RVM

apt install proxmox-backup-script

vi /etc/pbsbackup

Per backuppare su un Namespace (Solo buster) 

export BKP_REPO="PBS --ns mynamespace"


Manuale

  • Creare lo script:
cat | sudo tee /usr/local/sbin/pbsbackup << 'EOFile'
#!/bin/bash

source /etc/pbsbackup

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

backup-pre

proxmox-backup-client \
    backup \
    root.pxar:$BKP_PATH  \
    --repository $BKP_SRV:$BKP_REPO \
    --all-file-systems

backup-post
EOFile
  • Renderlo eseguibile:
chmod +x /usr/local/sbin/pbsbackup
  • Creare il file di configurazione:
vi /etc/pbsbackup

#!/bin/bash
export BKP_PATH="/media/backup"
export BKP_SRV="10.11.12.13"
export BKP_REPO="PBS"
export PBS_PASSWORD="secrepassWord"
  • Creare il fiel di cron:
cat | sudo tee /etc/cron.d/pbs << EOFile

MAILTO=admin@example.com

#min    hours   DayOfMonth      Month   DayOfWeek user command
00      22      *               *      *          root /usr/local/sbin/pbsbackup > /dev/null
EOFile
  • Provarlo
/usr/local/sbin/pbsbackup

Autenticazione user con un token con diritti solo su quel datastore=

  • Creare uno user in PBS, con una passowrd che non si userà:
Configuration/Access Control/User Management
  • Creare un API Token correlato allo user appena creato in:
Configuration/Access Control/API Token
  • Assegnare le permission allo user:
Configuration/Access Control/Permission/Add Permission

Add
User Permission

Path: /datastore/DATASORE-NAME
User: username
Role: /datastore/PBS-MEN
  • Assegnare le permission SIA allo user che all'API Token:
 Configuration/Access Control/Permission/Add Permission

Configuration/Access Control/Permission/Add Permission

Add
API Token Permission

Path: /datastore/DATASORE-NAME
API Token: tokenname
Role: /datastore/PBS-MEN


  • Creare
PBS_PASSWORD=70185333-b696-478a-a0d5-3bfe302b9091

#min    hours   DayOfMonth      Month   DayOfWeek user		command

00      22      *               *      *          root		proxmox-backup-client backup root.pxar:/ etc-pve.pxar:/etc/pve --repository username@pbs\!backup@servername.example.priv:DATA
