This is an old revision of the document!

This has been more difficult than I would have thought. I have used rsnapshot the past couple of years (2020-21), but have never really been happy with it for many reasons. The main reason is that it has never worked well, the rsync is reasonably fast, but the rsnapshot takes far too long. Other problems include; difficulties in set-up, and concerns will reliability. Recently I noticed that Debian no longer includes it in its repositories as of Debian 11 due to poor maintenance….. So I have no moved to Restic, which is described here: Back-up Server Setup.

overlayfs

I was disappointed with overlayfs, it does not seem to allow for a true merge file system, just overlay file system. The information available to set up was some of the worst I have found to date for Linux in the modern day. It is the only solution built in the Kernel. I looks like it may be of some use with containers, such as Docker. It does not really interest me at this time and I am not using.

tl;dr;

mergerfs

In the end I has stopped using mergerfs. There are other options to combine drives, e.g. lvm or simplely using symlinks.

tl;dr;

Mergerfs looks more like what I wish to achieve it is a way to pool drive into a common mount point. Below are some links with information and and possible setups.

Down load the current correct version of mergerfs from: https://github.com/trapexit/mergerfs/releases/, hint look at the link of the file of interest….: wget https://github.com/trapexit/mergerfs/releases/download/2.29.0/mergerfs_2.29.0.ubuntu-xenial_amd64.deb

Then load it into linux: sudo dpkg -i mergerfs_2.29.0.ubuntu-xenial_amd64.deb

Then create a mount point directory, e.g. /srv/storage, sudo mkdir /srv/storage sudo vim /etc/fstab

LVM

With the availability of Gparted to adjust partitions on the run I do not know if LVM is required any more. It does however look like a flexible system.

NFS

To mount a NFS manually:

sudo mount -t nfs -o rw,vers=4 192.168.1.5:/export/Disk1 /mnt/backup1
sudo mount -t nfs -o rw,vers=4 192.168.1.5:/export/Disk2 /mnt/backup2

Where:

-t nfs : type nfs
-o : options, options are separated by commas with no spaces
- rw : read / write
- vers=4 : version 4 of nfs
192.168.1.5:/export/Disk1 is the remote exported NFS mount point
/mnt/backup1 : is the local mount point, note this directory must exist, ideally empty, any existing contents are usually invisible and otherwise ignored

To unmount:

sudo umount /mnt/backup1
sudo umount /mnt/backup2

Where:

/mnt/backup1 is the local mount point to be unmounted

Possible mount script

#!/bin/bash
 
#input 1 is the proposed mount point
 
if [ -z "$1" ]
then 
   exit 11  #no mount point input, exit with error
else
   mount1=$1 #Use mount point input
fi
 
if grep -qs "$mount1" /proc/mounts; then
  exit 0  #Already mounted, exit with success
else
  mount "$mount1"
  if [ $? -eq 0 ]; then
   exit 0  # Successfully mounted, exit with success
  else
   exit 12 # mount failed, exit with error
  fi
fi

Created script to mount backup1 sudo bash ~/Myscripts/mount_backup1.sh to run

''sudo vim ~/Myscripts/mount_backup1.sh''

else
  mount -t nfs -o rw,vers=4 192.168.1.5:/export/Disk1 /mnt/backup1
  if [ $? -eq 0 ]; then
   exit 0  # Successfully mounted, exit with success
  else
   exit 12 # mount failed, exit with error
  fi
fi

Created script to mount backup2 sudo bash ~/Myscripts/mount_backup2.sh to run

''sudo vim ~/Myscripts/mount_backup2.sh''

#!/bin/bash
#Script to mount NFS remote Disk2 to local /mnt/backup2

  exit 0  #Already mounted, exit with success
else
  mount -t nfs -o rw,vers=4 192.168.1.5:/export/Disk2 /mnt/backup2
  if [ $? -eq 0 ]; then
   exit 0  # Successfully mounted, exit with success
  else
   exit 12 # mount failed, exit with error
  fi
fi

As we intend to shutdown the backup server it is good to unmount the back-up drives first.

Created script to unmount backup1 sudo ~/Myscripts/unmount_backup1.sh

''sudo vim ~/Myscripts/unmount_backup1.sh''

#!/bin/bash

   exit 0  # Successfully unmounted, exit with success
  else
   exit 12 # umount failed, exit with error
  fi
else
  exit 0 # Not actually mounted, exit with success
fi

Backup main Media drive (Rsync / Rsnapshot method)

Sadly I have found Rsnapshot and Rsync is not suitable for large backup service. Rsnapshot is simply too slow and I am concerned with reliability. Rsnapshot configuration is overly complex, with strange requirements such as tab for white space. As of Debian 11 it is no longer even included in the Debian repositories for lack of maintenance. It feels effectively abandoned.

Superseded, tl;dr;

I do not use Rsnapshot anymore. I just do not feel comfortable using it.
The following is the command I use to backup my main media drive: sudo rsync -av -u --delete /media/disk2/Media/ baumkp@192.168.1.5::all/media/Disk4/disk2 --exclude=snapraid.* --exclude=.Trash* --exclude=lost* >tmp.txt

I have rsync setup running as a daemon on 192.168.1.5 with login details for baumkp setup on the sever accepting input from the local area network to just the one address 192.168.1.10. On the remote machine 192.168.1.5: sudo vim /etc/rsyncd.conf

# create new
  
# any name you like
[all]
# destination directory to copy
path = /
# hosts you allow to access
hosts allow = 192.168.1.10
#hosts deny = *
list = true
uid = root
gid = root
read only = false
#auth users = baumkp
#secrets file = /etc/rsyncd.secrets

sudo vim /etc/rsyncd.secrets

username:userpassword

Use systemd systemctl from control of the deamon: sudo systemctl status rsync.service [status, start, stop, restart, reload, disable, enable] I have enabled so the rsync deamon this normally running.

The local directory /media/disk2/Media/ contents are to be backed up.

rsnapshot backups

I have 2 rsnapshot backup configurations;

/etc/rsnapshot1.conf To run locally: sudo rsnapshot -c /etc/rsnapshot1.conf daily

sudo vim /etc/rsnapshot1.conf

As these backup are made to nfs mounts it is very important the at nfs drive are mounted, or the backups will go into the local mount points and fill the local disks.
