[SOLVED] No Arch in BIOS after replacing home with backup home

colorpurple21859 · 09-28-2020, 10:54 AM

first check ownership of the backup /mnt/sdc

Code:

ls -l /mnt/sdc

or

Code:

 ls -Rla /mnt/sdc

to check recursively plus hidden files
post the output.

maybe this way

Code:

cp -rp /mnt/sdc /mnt/sda3/home/

So :
1 check permissions of backup files. If they're personnal files (photos, music, documents as pdf,odt,doc files) that would not matter much, you can easily correct after restoring, otherwise you will have to copy preserving ownership and write/read permissions
2 be root (really logout from user), telinit 1 at best, and backup then brand new user folder then copy the backedup user folder in home recursivly
3 check file permissions and correct them if needed
4 reboot

What is in /mnt/sdc? home folder plus sub-directories or <user folder> plus sub-directories?

Your command is attempting to copy the folder /mnt/sdc which would include everything in it to /home

Code:

I had to reinstall Arch due accidentally moving the /root directly, so I did it and then I tried to replace the vanilla /home with my backup /home

If your doing this from the installer, change the cp to this:

Code:

cp -ax /mnt/sdc/home/<user directory> /mnt/sda3/home/

If not doing this from a the installer, but by booting into the installed system, don't mount /dev/sda3 to /mnt it is already mounted on /, mount your backup as you have been, it would be this

Code:

cp -ax /mnt/sdc/home/<user directory> /home/

If the system didn't work when coping all the files from the backup to the root partition was probably due to the the root files in the backup belonging to your user user instead of root root

thx ! it works now! is there a way to add a branch from backup or so, so i havent to install all the programms again?

If you use the chown command to change permissions on /mnt/sdc, like this

Code:

chown -hR root /mnt/sdc
chown -hR <user name> /mnt/sdc/home/<usr directory>

should allow you to copy everthing from the installer with this

Code:

cp -ax /mnt/sdc/* /mnt/sda3/

if you have to do it again
you will need to add this mount command to the list

Code:

mount /dev/sda1 /mnt/boot

before copying everything over.

If your first problem is solved, mark the thread as solved.

New question, new thread. Thx

If you happen to break your system like this last time, format your partitions, mount the the partitions copy files over from the back-up, chroot and reinstall grub

by using this i get

Code:

 chown: invalid user: ▀myusername▀

you will have to change ownership back to the user either from the chroot or after booting the system with

Code:

chown -hR <user name> /home/<usr directory>
