So using this as a template: https://forums.mageia.org/en/viewtopic.php?f=41&t=5957
I've come up with
- Code: Select all
#! /bin/sh
#lifesaving backup mechanism from Mageia.org
#Used to back up filesystem prior to updating
rm -rf /srv/exthdd/fsback/backup6
mv /srv/exthdd/fsback/backup5 /srv/exthdd/fsback/backup6
mv /srv/exthdd/fsback/backup4 /srv/exthdd/fsback/backup5
mv /srv/exthdd/fsback/backup3 /srv/exthdd/fsback/backup4
mv /srv/exthdd/fsback/backup2 /srv/exthdd/fsback/backup3
mv /srv/exthdd/fsback/backup1 /srv/exthdd/fsback/backup2
cp -al /srv/exthdd/fsback/backup0 /srv/exthdd/fsback/backup1
rsync -av --delete --exclude /dev --exclude /tmp --exclude /home --exclude /media --exclude /proc --exclude /sys --exclude /mnt --exclude /var/tmp --exclude /var/cache --exclude /srv/exthdd --exclude /srv/owncloud / /srv/exthdd/fsback/backup0
Trouble is I've over complicated the file system/mountings.
This is actually a raspberry pi system (not magiea at this point, but fedora).
I originally had the /boot and / partitions on the sd card as usual, but then added an external HDD mounted at /srv/exthdd for the owncloud/nextcloud data directory.
I've since moved / to the hdd on another partition as well, so

So in /srv are two directories, one is simply for owncloud, which then links back to /srv/exthdd/owncloud/data, from when I first added the hdd to the system.
- Code: Select all
ls -al /srv
total 16
drwxr-xr-x. 4 root root 4096 Feb 11 03:07 .
dr-xr-xr-x. 19 root root 4096 Jul 26 2016 ..
drwxr-xr-x. 7 root root 4096 Jul 22 20:58 exthdd
drwxr-xr-x. 2 apache apache 4096 Oct 3 2016 owncloud
[root@localhost /]# cd /srv/owncloud/
[root@localhost owncloud]# ls -al
total 8
drwxr-xr-x. 2 apache apache 4096 Oct 3 2016 .
drwxr-xr-x. 4 root root 4096 Feb 11 03:07 ..
lrwxrwxrwx. 1 apache apache 25 Oct 3 2016 data -> /srv/exthdd/owncloud/data
Now my issue is, when I test run the rsync line from the backup script
- Code: Select all
rsync -av --delete --exclude /dev --exclude /tmp --exclude /home --exclude /media --exclude /proc --exclude /sys --exclude /mnt --exclude /var/tmp --exclude /var/cache --exclude /srv/exthdd --exclude /srv/owncloud / /srv/exthdd/fsback/backup0
It includes /srv and all it holds, which makes the backup hugely slow and massive.
What am I doing wrong or missed out? All help appreciated.
