Custom firmware build for R7800 v. 1.0.2.63SF

[Sizzlechest]

You have more than one USB device mounted, or have had since boot, since you run commands from sdb1 instead of sda1.
(Or you change command to use sdb1)

Or use the volume name, which should always be the same.

EDIT: Voxel's scripts use /tmp/mnt/$1 instead.

Work, but

root@R7800:~$ /mnt/sda1/router_backup.sh
tar: Removing leading `/' from member names
tar: Removing leading `/' from hard link targets
tar: /etc/dnscrypt.conf: Cannot stat: No such file or directory
tar: /etc/netwall*.conf: Cannot stat: No such file or directory
tar: /opt/scripts/firewall-*start.sh: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors

Do I just remove these from script?

Is there a chance the script is in DOS format instead of Unix?

Is there a chance the script is in DOS format instead of Unix?

How I do that?

 

[Sizzlechest]

How I do that?

dos2unix script.sh

Check the size before and after. If it's smaller after you run that command, it was probably in DOS format.

dos2unix script.sh

After that:

Add the P switch for tar to allow absolute names. The rest of these files don't exist on mine, so maybe the paths are wrong?

The script:

#!/bin/sh
#----------------------------------------------------------------------
# router_backup.sh
#----------------------------------------------------------------------
BACKUPFILE=/mnt/sda1/R7800backup.tar.gz
BUP="\
/etc/profile
/etc/rc.local
/etc/dropbear
/etc/init.d/stubby
/etc/dnscrypt.conf
/etc/dnscrypt-proxy-2.toml
/etc/openvpn/config/client
/etc/dnsmasq.conf
/etc/*hosts
/etc/netwall*.conf
/opt/scripts/firewall-*start.sh
/root/.ssh/authorized_keys

cd /
X=$(echo "$BUP" | xargs)
tar -czhf ./${BACKUPFILE} ${X}
sync

 

[Sizzlechest]

The script:

Yes, what I'm telling you is that you need to add the P switch to the tar command:

tar -czhPf ./${BACKUPFILE} ${X}

and the errors where it cannot find the files to backup are probably because the file doesn't exist.
