Backup Script für Minecraft Server unter Linux
Ein kleines Bash script zum automatische sichern eines Minecraft Servers auf ein lokales und zwei externe Verzeichnisse. Wobei die externen einmal über Samba und einmal per ssh erreicht werden.
#!/bin/bash
# Don't forget to make the script executable
# - cron
# if running the script hourly, daily or weekly
# just copy it to the corresponding folder in
# /etc/cron.hourly
# /etc/cron.daily
# /etc/cron.weekly
#
# if this is not enough, open crontab editor with
# >>crontab -e
#
# minute hour day-of-month month day-of-week command
#
# eg
# 0 3 * * * /path/to/backup.sh
#
# will run the script every day at 3am
#
# ----------------------------------------------
#
# for the SMB share you need to install cifs.
# >>sudo apt-get install cifs-utils
#
# create a folder in /mnt for backup inclusion
# >>sudo mkdir /mnt/backup
#
# to mount the shared folder from smb manually:
# sudo mount -t cifs //smb/path/folder /mnt/backup -o user=nobody
#
# to mount the shared folder automatically at reboot open the file "/etc/fstab" as root
# add one line in the following format:
# //smb/path/backup /mnt/backup cifs defaults,rw,username=YOURWINUSER,password=YOURWINPASSWORD,file_mode=0777,dir_mode=0777 0 0
#
# this should mount the shared folder at start up if available.
# Run "umount /mnt/backup;mount -a" after changing the fstab file to test out the changes
#
# -----------------------------------------------
#
# to install 7z use
# >> sudo apt-get install p7zip-full
#
#
# good luck
