Steps

 $ ssh epp@10.0.0.9

 $ sudo mount /dev/sdb1 /media/backup

 $ cd /media/backup/

If it fails, do it a second time. 

 $ source rainier_backup.sh
      tar: Removing leading `/' from member names

 $ cd

 $ cd dbbackup/

zdome MediaWiki 

 $ ls dbbackups/wikidb/
       wiki-20200124T2021.tgz  wikidb-20200124T2021.sql.gz

 $ cd

 $ sudo umount /media/backup/

 $ exit
       logout
       Connection to 10.0.0.9 closed.

Backup Files

Location on the backup disk

rainier's Mediawicky 

 $ pwd
     /media/backup/rainier/home/epp/dbbackup/dbbackups/wikidb

Hood and Rainer sync directories 

 $ pwd
     /media/backup/hoodcd 

 $ pwd
     /media/backup/rainier



These notes will help with a known hosts problem. 

 $ ssh-keygen -f "/home/epp/.ssh/known_hosts" -R 10.0.0.111
       # Host 10.0.0.111 found: line 1 type ECDSA
       /home/epp/.ssh/known_hosts updated.
       Original contents retained as /home/epp/.ssh/known_hosts.old

rsync

  • No backup the NUC. See below for creating the backup disk. 
 sudo mount /dev/sdb1 /media/backup
 cd /media/backup
 sudo rsync -ax /home .
 sudo umount /media/backup

Other rsync examples 

rsync -ax / /media/cd181ea6-154d-4070-ab22-bd4f5f5aa635/tabor120520
rsync -ax -exclude /home/eepp/scr/linux-source-2.6.32 …
rsync -ax pi@10.0.0.161: pi

add --delete on future syncs

I dropped the auto mount and duplicity backup.

Sisters

 cd /media/eepp/0c9f950a-f453-4993-b2c0-da69b5d3da1d/

 mkdir sisters

 cd sisters/

 sudo rsync -ax /home/ .

 sudo rsync -ax /opt/ .

Create the Backup Disk

Determine what disk are currently on the system. The Icy Dock disk is ext2 so it will be re-partitioned and formated 

 mount

or 

 sudo parted -l
 sudo parted /dev/sdbeepp@rainier:~$ sudo parted /dev/sdb

 eepp@rainier:~$ sudo mkdir /media/backup
 eepp@rainier:~$ sudo mount /dev/sdb1 /media/backup/

Note - If you are starting with a formated disk

  • I right clicked in each partition and did a delete
  • Repeated until everything was free space
  • I then created one simple volumn

Mount at Boot

 sudo mkdir /media/backup
 sudo chmod 777 /media                   # these were 755
 sudo chmod 777 /media/backup

 epp@rainier:/media/backup$ diff /etc/fstab /etc/fstab.org
