====== Using CIFS/SMB with Proxmox Backup Server 3 ======
  * By default, Proxmox Backup Server expects
    * Local storage
    * SSD storage
  * PBS can work with CIFS/SMB or NFS storage and HDDs, but restoring backups will be very slow.
    * By slow I mean around 40 minutes to restore a 60GB virtual machine.
    * But for some, like me, the storage savigs are worth the performance tradeoff
    * I would not recommend this in a corporate production environment, but it is perfectly fine for a homelab.
===== Setting up CIFS share =====
  * Unlike in PVE, there is no GUI way to mount a CIFS share
  * We will have to do it manually
  * Add the following to your /etc/fstab file <code>//serverip/networkshare /media/localfolder cifs vers=3.0,credentials=/root/.smbcredentials,iocharset=utf8,file_mode=0777,dir_mode=0777,uid=34,gid=34</code>
    * Let me guide you on how to put the proper parameters where
    - First is IP slash Network share where you want to put the PBS datastore
    - Second is the local folder on the PBS filesystem where it will be mounted
    - Third is saying fstab we want to use SMB and it's version (in this case 3.0)
    - Fourth is path to location of our credentials file
        * You can put username and password into fstab but it is not a good idea
        * The .smbcredentials file will contain username and password that can read and write to the network share we want to store in, ie <code>//serverip/networkshare</code>
        * Example content of the .smbcredentials file <code>username=serviceuser
password=o8nbarm4agsrip8kef</code>
        * After creating the file and adding these two lines into it we need to protect it, so run <code>chmod 400 ./smbcredentials</code>
    - Rest is what character set we will use, what chmod will created files and folders me (0777 isn't secure but it's simple and it works)
    - Last, uid and gid is imporant. 34 is the user ID of the proxmox "backup" user, which has to appear to PBS as the owner of the /media/localfolder folder
    * Example of a full fstab entry <code>//nas.laptopwiki.local/backups/pbs /media/nas cifs vers=3.0,credentials=/root/.smbcredentials,iocharset=utf8,file_mode=0777,dir_mode=0777,uid=34,gid=34</code>
===== Adding a datastore =====
  * In PBS, in the left menu, click Add Datastore
  * Name is what will it be listed as and what we will need to use when we add it to Proxmox VE
  * Let's call it "datastore1"
  * Backing path is the full **local** path of the network share we set up in previous step, so "/media/nas"
  * Add the datastore
  * If you are on HDDs, this will take a while. Mine took about 2 hours on a pair of Seagate Exos 16TB drives in RAID 1
===== Adding PBS datastore to Proxmox VE =====
  * In PVE, go to 
  - Datacenter
  - Storage
  - Add
  - Proxmox Backup Server
  * ID = what it will be called, let's call it "pbs1"
  * Server = IP/DNS name of your PBS server
  * Username = easiest is to use root@pam, that will add it as our root user we also use to log in into PBS
  * Password = password for our root user
  * Datastore = name of the datastore we created, in our case **datastore1**
  * Now go back into PBS and click on Dashboard
  * In the middle of the screen will be a Fingerprint button
  * Press that, copy the long string and paste it into our "Add Storage" dialog we have currently open in PVE.
  * Click Add
