1. If you only have one server, simply use tar and you are done. If you take your data seriously, you should consider a commercial network backup software that is friendly to Linux and open source like Arkeia. Arkeia Network Backup does hot backup of PostgreSQL, MySQL and about 100 linux distros (it even included in the Ubuntu and Mandriva repository).

2. I have an some files in cent os.I need to schedule auto backup that files to the another file storage server directory. I need that script.will you please anyone post that script.

   Source : Cent Os
   Destination : Samba File storage server( another directory).

3. a backup script on centos to take periodic backups , change the names and customize it for your system.

   #!/usr/bin/env bash
   #---------------------
   exit_on_error () {
       if [ $? -ne 0 ]; then
           logger -s "bezkon:backup script failed";
           exit 1;
       fi
   }
   
   
   # we are done with the mount
   # now try to create the date folder
   # in the "/media/backup_disk/database_snapshots" folder
   create_snapshot_folder ()
   {
       logger -s "bezkon:backup trying to create the snapshot folder";
       mkdir -p $1;
   }
   
   
   # try to copy the redis and mysql files to the destination folder.
   copy_files_to_snapshot_folder ()
   {
       logger -s "bezkon:backup trying to copy the database files to the folder";
       cp -rf "/var/lib/mysql/repository"/* $1;
       cp -rf "/dump.rdb" $1;
       cp -rf "/var/log/bezkon/"/* $1;
   }
   
   
   # unmount the file system as we are done with it
   unmount_backup_disk ()
   {
       logger -s "bezkon:backup unmounting the backup drive";
       umount $1;
       #remove the directory as we are done
   #    if [ -d "$1" ]; then
   #    logger -s "bezkon:backup Trying to remove the destination dir";
   #            rm -rf $1;
   #    fi
   }
   
   mount_backup_disk ()
   {
       logger -s "bezkon:backup Trying to mount the backup disk";
       #create the directory if its not present
       if [ ! -d "$2" ]; then
      logger -s "bezkon:backup Trying to create the destination dir";
      mkdir -p $2;
       fi
       mount $1 $2;
   }

   #    mount_backup_disk $mount_src $mount_dst;
   #    exit_on_error;
   #fi
   
   # get the current time of the day
   # and create the snapshot folder
   now=$(date +"%m-%d-%Y")
   snapshot_folder="/media/backup_disk/database_snapshots/snapshot_$now"

4. Hi,
   I am new to shell programing. I am working under REDHAT Linux and want a script which will enable me to backup one of my folder to external usb drive on hourly basis.
