Hallo,
I tried to find a solution to generate backups on the fly (without storing them local) on an ftp backup space. So I wrote this small script which is able to do that.
ATTENTION:
Do not use this script in productive environment or with an unstable FTP Server location (e.g. laggy cloud services). The script does not give a feedback on errors (there is only one stored on the FTP Server - so if its is broken there is no other backup)! Use at your own risk!
ATTENTION 2:
I switched to Syncovery CL for Linux so I am no longer supporting/maintaining this script. If you are using this script and want more (like incremental backups or SFTP/WebDav support) you my check out the new backup soltion I am using: click here.
Features:
- generates compressed .tar.gz archives on a ftp backups space during compression (no local space needed)
- wildcards for include and exclude paths
There are still some features missing so maybe one of you can help me to improve this script:
Encrypt the backups with passwordAdd SFTP supportBackup version history (delete only not needed backups from the ftp server)detect errors and send an email if there is one or more errors

- # Versions:
- # 1.0
- # - First release at i-mscp.net
- #
- # Requirements:
- # - ncftp (apt-get install ncftp)
- #
- # Tested with:
- # Ubuntu Server 12.04 LTS and 14.04 LTS
- #
- # It is prefered to run this script using crontab.
- # The following line shows an example to run it every day at 00:00 o'clock without any output
- # To generate an output you could use e.g. the "tee" command or let the output be sent to your email account by crontab
- # 0 0 * * * /root/backup.sh 2&>1 >/dev/null
- #
- # ATTENTION:
- # This script deletes and recreates the folder set by "FTPPATH" on EVERY backup run to clean old backups. There is no version history nor a setting how
- # much backups should be kept. So make sure that this folder is unique because the script is not checking what it deletes!
- # (It will delete everything in the "FTPPATH" before storing the new backup file in it!!)
- # e.g. if you set the FTPPATH to "/backups/imscp/" the script will delete the folder "imscp" on every start and creates it again before storing files in it.
- # Configuration part:
- TARNAME="imscp" # name of the generated tar file e.g. TARNAME.tar.gz
- FTPUSER="" # username of your backup account
- FTPPASS="" # password of your ftp account
- FTPHOST="" # host address of your ftp account
- FTPPATH="" # path inside the ftp account e.g. "/backups/imscp/" - this should be UNIQUE! (read the "ATTENTION" part above!!!)
- LOCALBACKUP="/home/ /root/ /var/www/virtual/*/backups/ /etc/ /var/mail/ /var/www/imscp/gui/plugins/" # paths to save in the backup (* is allowed)
- EXCLUDEPATHS="/etc/apache2/*/access.log" # paths to exclude from the backup (* is allowed)
- # DO NOT CHANGE BELOW!!! (Script starts here)
- #remove previouse generated file list
- echo -n "Removing old backup file lists..."
- rm /tmp/tar_$TARNAME.lst
- rm /tmp/tar_exclude_$TARNAME.lst
