simple backup script using rsync + tar

backup.sh

#!/bin/bash
TODAY=$(date +%Y%m%d)
TARGETS=( '/etc' '/home' '/root' '/var/www' )
BACKUP_ROOT='/backups'
BACKUP_DIR="${BACKUP_ROOT}/${TODAY}"

echo "$(date +%D" "%r): Beginning backup"
mkdir -p $BACKUP_DIR

for i in ${TARGETS[@]}; do
    if rsync -Ra $i ${BACKUP_DIR}; then
        echo "Successfully backed up $i"
    else
        echo "Failed backing up $i"
    fi
done

if tar -czf "${BACKUP_DIR}.tgz" $BACKUP_DIR &> /dev/null; then
    rm -rf $BACKUP_DIR
    echo "Successfully compressed ${BACKUP_DIR}"
else
    rm -rf $BACKUP_DIR
    echo "Failed compressing ${BACKUP_DIR}.tgz"
    echo "$(date +%D" "%r): Backup failed"
    exit 1
fi

echo "Removing backups older than 30 days"
find $BACKUP_ROOT -name '*.tgz' -mtime +30 -delete -print
echo "$(date +%D" "%r): Backup complete"

Hi Alex,
Thanks for this script.
Could you please help how to modify this script , if your backup directory is in remote server.

Since it's already using rsync to copy locally, you should be able to add the remote server's ip to backup_root and it should Just Work™

backup_root=1.2.3.4:/backups

Hi Alex,

Thanks for your reply. I will check and update you.

Hi ALex,
My requirement for backup script is as below,

1. local server : 192.168.0.1/24 & Remote server : 192.168.0.5/24
2. archieve the $targets and save it in Remote server path (192.168.0.5:/backup)
3. rsync the $backup_dir with the local directories

I have modified your script accordingly , kindly check the script
#!/bin/bash
today=$(date +%m%d%Y)
#local_server_targets
targets=( '/var/www' '/etc' )
#Remote server IP & path
backup_root='192.168.0.5:/backup
backup_dir=${backup_root}'/'${today}
#logs
log='/var/log/backup.log'

echo "$(date +%D" "%r): Beginning backup" >> $log
mkdir -p $backup_dir

for i in ${targets[@]}; do
rsync -Ra $i ${backup_dir}
if [[ $? -eq 0 ]]; then
echo "Successfully backed up $i" >> $log
else
echo "Failed backing up $i" >> $log
fi
done

tar -czf $backup_dir'-backup.tgz' $backup_dir &> /dev/null
if [[ $? -eq 0 ]]; then
echo "Successfully compressed ${backup_dir}" >> $log
else
echo "Failed compressing ${backup_dir}.tgz" >> $log
fi

Remove uncompressed, duplicated files. Backups are saved in $backup_root

rm -rf $backup_dir

echo "Removing backups older than 30 days" >> $log
find $backup_root -mtime +30 >> $log
find $backup_root -mtime +30 -exec rm {} ;

echo "$(date +%D" "%r): Backup complete" >> $log

Please let me know , if you want me to make any changes to your script to meet the above mentioned requirements.

Looks good. Feel free to fork this gist and modify it for your own use. That's gonna be the best way to make it work for your specific use case.

Hi alexcreek,
Many thanks for your code. Simple and efficient

Hey @alexcreek,
Thanks for this script, just what I needed. And it's simple enough.

thanks for the scrypt, can you make one to restore?
