Backup data: Windows 7 to Linux using Cygwin's rsync
I thought I would share the bash script I wrote (for Cygwin) to backup my files and photos from my main Windows 7 PC to both my HP Microserver (running Ubuntu using raid-z!) and a local external USB HD.
Here are some pre-requisites for running the script (I might have missed some, so if it doesn’t work please let me know and I can correct the post).
- Install Cygwin
- [Optional] Set up keys to authenticate between Cygwin and Linux
- Set up an rsync daemon on the Linux box
- Save my script below as
copy.sh(to your cygwin user home dir e.g.C:\cygwin\home\username) - Customise it for your PC and to fit your needs and run on Cygwin:
sh copy.sh -a
#!/bin/bash

usage()
{
cat >> EOF
This script backs up stuff to the server (default) or local disk 'e:'.
OPTIONS:
p - photos
f - files
a - all
l - local
t - test (rsync -n)
Usage examples:
sh copy.sh -al :: backup all to the external HD
sh copy.sh -p :: backup photos to the backup server.
EOF

rsync $TEST $NORMAL_OPTS $REMOTE_OPTS --exclude 'tmp' /cygdrive/m/files/{stuff,important\ docs} $BACKUP_PATH/files/

# you could instead use SSH instead by adding the following options to REMOTE_OPTS
# -e "ssh -c blowfish-cbc"
# and change the BACKUP_PATH to:
# username@server:/backup
