Centmin Option 21

There's very detailed centmin.sh menu option 21 documentation for Centmin Mod 131.00stable and Centmin Mod 140.00beta01. There are separate links as documentation will eventually diverge as Centmin Mod 140.00beta01 development continues to improve on the code.

Yes it does leave source data intact so you can run it multiple times for testing. Just be aware that each backup run will take up disk space on your source data/original server so ensure you have enough free disk space.

Rough idea of data set size for Centmin Mod standard install can be found via these commands unless you have saved data outside of these standard directories and their respective subdirectories.

Code (Text):

du -sh /usr/local/nginx /home/nginx /root/tools /var/lib/mysql /root/.acme.sh

If it's a test you can always run a test VPS with test data and then treat that as source data and do a test migration on to a 2nd test VPS until you are familiar with the process and ready for live server migration.

 

They're just directories within /home/databackup so delete them like any other directory or if you want to start fresh, just delete /home/databackup and it will delete everything within it

 

if you are unsure of a linux command, tag --help or -h to end and it will give you the supported options

Code (Text):

rm --help
Usage: rm [OPTION]... [FILE]...
Remove (unlink) the FILE(s).

  -f, --force           ignore nonexistent files and arguments, never prompt
  -i                    prompt before every removal
  -I                    prompt once before removing more than three files, or
                          when removing recursively; less intrusive than -i,
                          while still giving protection against most mistakes
      --interactive[=WHEN]  prompt according to WHEN: never, once (-I), or
                          always (-i); without WHEN, prompt always
      --one-file-system  when removing a hierarchy recursively, skip any
                          directory that is on a file system different from
                          that of the corresponding command line argument
      --no-preserve-root  do not treat '/' specially
      --preserve-root[=all]  do not remove '/' (default);
                              with 'all', reject any command line argument
                              on a separate device from its parent
  -r, -R, --recursive   remove directories and their contents recursively
  -d, --dir             remove empty directories
  -v, --verbose         explain what is being done
      --help     display this help and exit
      --version  output version information and exit

By default, rm does not remove directories.  Use the --recursive (-r or -R)
option to remove each listed directory, too, along with all of its contents.

To remove a file whose name starts with a '-', for example '-foo',
use one of these commands:
  rm -- -foo

  rm ./-foo

Note that if you use rm to remove a file, it might be possible to recover
some of its contents, given sufficient expertise and/or time.  For greater
assurance that the contents are truly unrecoverable, consider using shred.

Out of habit to not delete the wrong directories and limit damage, I usually change into the directory I want to delete. Make it a habit

Code (Text):

cd /home/databackup
rm -rf /home/databackup
