[gentoo-user] backing up system files

[Philip Webb]

My recently-built machine has an SSD for everyday storage
+ an HDD for less often used stuff + back-ups (in dir  /y ).
To avoid having to re-install the system if the SSD collapses one day,
I wanted to make a simple back-up copy of vital files on the HDD.
There are lots of apps in 'app-backup' & I looked at  3
-- Backintime, Luckybackup, Kbackup -- , which did the job,
tho' configuring them took a bit of concentration.
I also wrote a simple Bash script, which also does the job very well
& which has caused me to remove the GUI apps & use it instead;
it uses  2  exclude files & the code is below (from  /usr/local/bin/ ).

  root:510 bin> cat bsys
  #!/bin/bash
  mount /dev/sdb8 /y
  rsync -av /bin /y/bkp-sys
  rsync -av /etc /y/bkp-sys
  rsync -av /lib32 /y/bkp-sys
  rsync -av /lib64 /y/bkp-sys
  rsync -av /opt /y/bkp-sys
  rsync -av /root /y/bkp-sys
  rsync -av /sbin /y/bkp-sys
  rsync -av /usr --exclude-from '/usr/local/bin/bsys-usrx' /y/bkp-sys
  rsync -av /var --exclude-from '/usr/local/bin/bsys-varx' /y/bkp-sys
  umount /y
  echo "done"
  
  root:508 bin> cat bsys-usrx
  # bsys-usrx : 121116 -- files to exclude from /usr
  local/
  portage/
  src/
  
  root:509 bin> cat bsys-varx 
  # bsys-varx : 121116 -- files to exclude from /var
  empty/
  log/emerge-logs/
  tmp/

HTH others.
