S3cmd : Used to copy files to s3 bucket from server. AWS

S3cmd : AWS command used to copy/Sync content to S3 bucket

s3cmd can be installed from epel repo or by manually compiling the code.

While installing from epel there could be dependency issue for the python.
while using epel repo we need the python version 2.4 in the server if you are having another version of python its better to go with the manual installation.

## RHEL/CentOS 6 32-Bit ##
# wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
# rpm -ivh epel-release-6-8.noarch.rpm

## RHEL/CentOS 6 64-Bit ##
# wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# rpm -ivh epel-release-6-8.noarch.rpm

yum install s3cmd

For manual installation Download the tar file from

http://sourceforge.net/projects/s3tools/files/s3cmd/

get the tar file of the needed version .
make sure you have a python version > than 2.4 installed in the server.

untar the file using tar zxvf or zjvf as per the need and use python to run the installation script

python setup.py install

..

When using secure HTTPS protocol all communication with Amazon S3
servers is protected from 3rd party eavesdropping. This method is
slower than plain HTTP and can't be used if you're behind a proxy
Use HTTPS protocol [No]: Yes

Test access with supplied credentials? [Y/n] Y
Please wait, attempting to list all buckets...
Success. Your access key and secret key worked fine :-)

Now verifying that encryption works...
Success. Encryption and decryption worked fine :-)

Save settings? [y/N] y

—exclude / —include — standard shell-style wildcards, enclose them into apostrophes to avoid their expansion by the shell. For example --exclude 'x*.jpg' will match x12345.jpg but not abcdef.jpg.
—rexclude / —rinclude — regular expression version of the above. Much more powerful way to create match patterns. I realise most users have no clue about RegExps, which is sad. Anyway, if you’re one of them and can get by with shell style wildcards just use —exclude/—include and don’t worry about —rexclude/—rinclude. Or read some tutorial on RegExps, such a knowledge will come handy one day, I promise ;-)
—exclude-from / —rexclude-from / —(r)include-from — Instead of having to supply all the patterns on the command line, write them into a file and pass that file’s name as a parameter to one of these options. For instance --exclude '*.jpg' --exclude '*.gif' is the same as --
