Backup script to split and tar files

Hi Guys,

I'm very new to bash scripting. Please help me on this.

I'm in need of a backup script which does the ff.

1. If a file is larger than 5GB. split it and tar the file.
2. Weekly backup file to amazon s3 using s3rsync
3. If a file is unchanged it doesn't need to copy to amazon s3

I've searched google and can't find a script that suit my needs.

Can anyone post some of their scripts or links for reference which may help?

Thank you.

BACKUP.D(5)							backupninja package						       BACKUP.D(5)

NAME
BACKUP.D - Action configuration files for backupninja(1). SYNOPSIS
/etc/backup.d/* DESCRIPTION
To preform the actual backup actions, backupninja processes each action configuration file in /etc/backup.d according to the file's suffix. .sh run this file as a shell script. .rdiff backup action for rdiff-backup. .dup backup action for duplicity. .maildir backup action for slow, incremental rsyncs of tens of thousands of maildirs. .mysql backup action for safe MySQL dumps. .pgsql backup action for safe PostgreSQL dumps. .sys backup action for general system reports and hardware information. .svn backup action for safe backups of subversion repositories. .trac backup action for safe backups of trac repositories. .makecd backup action for burning backups to CD/DVD or creating ISOs. These files must be owned by root and must not be world or group readable/writable. Support for additional configuration types can be added by dropping bash scripts with the name of the suffix into /usr/share/backupninja. The configuration files are processed in alphabetical order. However, it is suggested that you name the config files in "sysvinit style." For example: 10-local.pgsql.disabled 15-runthisfirst.sh 20-runthisnext.mysql 90-runthislast.rdiff Typically, you will put a '.rdiff' config file last, so that any database dumps you make are included in the filesystem backup. Action con- figurations which end with .disabled are skipped. Example templates for the action configuration files can be found in /usr/share/doc/backupninja/examples. You can also use ninjahelper(1), a console based "wizard" for creating backup actions. SCHEDULING
By default, each configuration file is processed everyday at 01:00 (1 AM). This can be changed by specifying the 'when' option in a backup action's config file or in the global configuration file. Special value 'manual' will disable scheduling for the backup action. It is pos- sible to run the backup action manually by invoking ninjahelper(1) with --run command line argument. For example: when = sundays at 02:00 when = 30th at 22 when = 30 at 22:00 when = everyday at 01 when = Tuesday at 05:00 when = hourly when = manual These values for "when" are invalid: when = tuesday at 2am when = tuesday at 2 when = tues at 02 A configuration file will be processed at the time(s) specified by the "when" option. If multiple "when" options are present, then they all apply. If two configurations files are scheduled to run in the same hour, then we fall back on the alphabetical ordering specified above. The "when" must occur before any sections in the action configuration file. FILE FORMAT
The file format of the action configuration files is "ini style." Sections are created by using square bracket. Long lines are connected with a backslash. For example: # this is a comment [fishes] fish = red fish = blue [fruit] apple = yes pear = no thanks i will not have a pear. SEE ALSO
