I am currently running a web-facing server with the root filesystem on an external USB disk with another USB disk attached and destined for backup of the server.

What I really need to do, however, is to have a full backup system running as a scheduled cron task, with incremental backups and/or compression, as well as an easy to run restore procedure or script.

My setup is as follows:

/dev/mmcblk0p1: LABEL="PI BOOT" UUID="6654-8624" TYPE="vfat"
/dev/sda1: LABEL="rootfs" UUID="6d300a32-1cd7-46ab-be6f-c30c2bc51519" TYPE="ext4"
/dev/sdb1: LABEL="The Pad Backup" UUID="ec33414c-b925-d101-a012-404cb925d101" TYPE="ext4"

Filesystem      Size  Used Avail Use% Mounted on
/dev/root       917G  3.9G  867G   1% /
devtmpfs        459M     0  459M   0% /dev
tmpfs            93M  1.4M   92M   2% /run
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           186M     0  186M   0% /run/shm
/dev/mmcblk0p1  968M   40M  929M   5% /boot
none            463M     0  463M   0% /sys/fs/cgroup

Please note: This is not about backing up an SD card

Any help would be greatly appreciated.

Cheers, Jack

  • Hi, maybe this article can be intereted for you : sysmatt.blogspot.cl/2014/08/… :) – Gilles Grandguillaume Nov 25 '15 at 20:50
  • Regarding your edit ("Please note this is not about backing up an SD card"), it does very clearly seem to be about backing up the root filesystem, which is the topic of the duplicate question. It doesn't matter what the medium is. There is not, e.g., a special backup system, written only for the raspberry pi, and more specifically only for filesystems on attached storage attached to a raspberry pi. That would be absurd and contradicts some basic premises of good software engineering. – goldilocks Nov 26 '15 at 14:00
  • ...Have an actual look at what's available and has been recommended, and if you can formulate a question about why none of these existing solutions are appropriate to your situation, then great -- but I am sure you cannot, unless there is some special information you have neglected to include here originally. – goldilocks Nov 26 '15 at 14:03
  • Hi Goldilocks, I must apologise if I have caused offence. When I saw the "Duplicate" notice, I got brassed off because I assumed the post I unwitting duplicated was about cloning one's SD card, something I have seen many posts about lately. I have since followed the link at the top of this page and found rsnapshot to be very useful and will be voting up the person who suggested it. – Pi Hard Nov 27 '15 at 3:35
