After restoring the whole raspbian system using rsync, I get following errors during boot.
systemd[1]: systemd-modules-load.service: Main process exited, code=exited, sta...
systemd[1]: systemd-modules-load.service: Failed with result ´exit-code´.
systemd[1]: Failed to start Load Kernel Modules.
After this also netfilter-persistent.service
and hostapd.service
fail to start.
What got corrupted here and how can I correct this?
Following are the steps how I do the backup.
I followed the answer to Can a Raspberry Pi be used to create a backup of itself? backup my running raspbian system. Instead of a USB drive, I use a rsync server for backup. Here is my setup and the commands I use.
Configuration of my rsync server:
$ cat /etc/rsyncd.conf
#global (globale einstellung)
log file = /var/log/rsync.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
timeout = 300
[rpi]
path = /mnt/sdb1/backups/rpi
comment = backup
max connections = 1
hosts allow = 192.168.0.2
hosts deny = *
use chroot = yes
list = true
uid = root
gid = root
read only = false
auth users = user
secrets file = /etc/rsyncd.secrets
On my Raspberry I execute following command to start the backup:
sudo rsync -aHv --numeric-ids --delete --exclude-from=/home/user/rsync-exclude.txt --password-file=/home/user/rsync-pass / rsync://user@192.168.0.1/rpi/rsync_backup/
Content of rsync-exclude.txt
$ cat rsync-exclude.txt
/proc/*
/sys/*
/dev/*
/boot/*
/tmp/*
/run/*
/mnt/*
/media/*
/var/swap
/var/log/*
To restore the content on the sdcard, I insert the Raspberrie's sdcard in the rsync server and mount the 2nd partition on this sdcard as /mnt/sdcard
. Afterwards I execute following command to start the restore.
sudo rsync -av --numeric-ids --delete-during /mnt/sdb1/backups/rpi/rsync_backup/ /mnt/sdcard/
When booting from this sdcard, I get the above described errors.
Update: I now updated my procedure so that also the boot partition is backed up and restored.
Please see the following snippets for error investigation.
