Backup Notes

Cygwin/Rsync backup

1. Install Cygwin, with these packages:

• Editors/vim
• Net/openssh (and dependencies)
• Net/rsync

2. Create backup config directory %USERDIR%\cygwin-backup

3. Add config files to backup directory:

• exception_list.txt (list of files to ignore)
• backuplist.txt (list of files/directories to back up, relative to the user profile path, Unix-style paths)
• backup.sh (below)
• backup.log (empty file)
• backup.bat (below)

4. Create script backup.sh:

!/bin/bash


echo

echo "backup started"

USERDIR="/cygdrive/c/Documents and Settings/"

BACKUPDIR=cygwin-backup

RSYNCACCT=1034

RSYNCSERV=usw-s001.rsync.net



date

cd "$USERDIR"

rsync -rvte ssh --exclude-from=$BACKUPDIR/exception_list.txt --delete --files-from=$BACKUPDIR/backuplist.txt . $RSYNCACCT@$RSYNCSERV:backups/ |tee -a $BACKUPDIR/backup.log 2>&1

scp $BACKUPDIR/backup.log $RSYNCACCT@$RSYNCSERV:backups/

ssh $RSYNCACCT@$RSYNCSERV "chmod -R 770 backups"

date

5. Create SSH keys, in Cygwin Bash shell (accept defaults, do not use passphrase):
ssh-keygen -t rsa

6. Copy SSH public key up to server:
scp .ssh/id_rsa.pub 1034@usw-s001.rsync.net:.ssh/authorized_keys

7. Make backup script executable:
chmod 775 /cygdrive/c/Documents\ and\ Settings//cygwin-backup/backup.sh

8. Test:
/cygdrive/c/Documents\ and\ Settings/Bill/cygwin-backup/backup.sh

9. Create backup.bat batch file for Windows scheduler (edit path to .sh script):

@echo off

C:

chdir C:\cygwin\bin

bash --login -i -c "/cygdrive/c/Documents\ and\ Settings/Bill/cygwin-backup/backup.sh"

10. Create schedule as desired, using Windows scheduler to launch the batch file (note a password for the user is required).

11. Change password for the backup location, and record password in intranet:
ssh -t 1034@usw-s001.rsync.net passwd
