Linux script ftchbkup - fetch backups from remote host.

I am based just outside Nottingham in the East Midlands and can readily provide on-site Linux training courses in Nottingham, Beeston, Castle Donnington, Chesterfield, Derby, East Leak, Grantham, Leicester, Lincoln, Loughborough, Mansfield, Market Harborough, Newark, Sheffield, Stoke on Trent and Sutton Ashfield. Off site training and public linux classes can be arranged in Nottingham and elsewhere in the East Midlands.

City LinUX sample scripts - ftchbkup

NAME

ftchbkup - fetches backups from remote host to a local repository.

SYNOPSIS

ftchbkup [ -c <config> ] [ -d ] [ -l ][ -v ] < hostname >

AVAILABILITY

ftchbkup is a Bourne shell script which should work equally well on all versions of UNIX, Linux and Mac OS X.

DESCRIPTION

ftchbkup uses the configuration file ( /usr/local/etc/ftchbkup.cf by default) to determine the location and age of the backup files to fetched from the remote host and the path to the local repository. The archives are fetched using lftp .

In order to save disk space in the local repository, archives older than the maximum age set in configuration file are deleted once the the latest files have been successfully downloaded.

OPTIONS

-c <config_file> Use the named configuration file in preference to the default /usr/local/etc/ftchbkup.cf .

-d Start in debug mode. The script will run in a shell with the -x option set.

-l Log each backup field retrieved from the target host using the syslog facility.

-v Set verbose mode. Ordinarily ftchbkup operates silently unless problems are detected. In verbose mode ftchbkup reports on each significant action.

EXAMPLES

ftchbkup -v caswallon-gw

Using the hostname " caswallon-gw " as the lookup key, ftchbkup will extract the details of the backup files to be fetched from the default configuration file /usr/local/etc/ftchbkup.cf , and fetch them from the remote server to the local repository.

BUGS

The script is quite crude having been developed to fetch archives from client servers hosted by 1and1. The use of the configuration file does however make it reasonably generic. File permissions are critical and sudo will be used within the script to execute the find command. With judicious use of the debug and verbose modes, permission and configuration problems should be relatively easy to resolve.

FILES

I started my career in computing in the days of CPM and C/CPM, building network operating systems and correcting bespoke software written to manage community transport booking and accounting systems.

I fist came across UNIX when called upon to migrate database systems from Mercator BBS to Thoroughbred Basic. Excited by the power and flexibility of UNIX in 1989/90 I studied the OS at City University night classes while developing my practical skills in a SCO Xenix environment during the working day.

In 1994 I was introduced to Linux by students in the School of Mathematics and Computing at North London University. Although initially sceptical of the ability of the fledgling OS to meet the requirements of large scale mission critical systems, I rapidly became a convert to Linux in a corporate environment.

I have now worked professionally as a systems manager and systems administrator with Xenix, AIX, HPUX, SunOS, Solaris and Linux in the City, Antwerp, McLean Virginia, Cairo, Birmingham and Nottingham for over 25 years
