After restoring the whole raspbian system using rsync, I get following errors during boot.
systemd: systemd-modules-load.service: Main process exited, code=exited, sta... systemd: systemd-modules-load.service: Failed with result ´exit-code´. systemd: Failed to start Load Kernel Modules.
After this also
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://firstname.lastname@example.org/rpi/rsync_backup/
$ 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.
