Best backup tools in Linux.

Data lose is one of the major fears of the users.Disk failures & accidents are the common cause of data lose which can occur at any time, so it's really important to keep track of our data regularly.
Backup tools comes with various features:
-enable you to identify important files and directories that are then constantly monitored and regularly backed up.
-perform incremental backups, which – after making a complete initial imprint of the directory – will then only make copies of new files or those that have changed since the last backup inorder to tackle redundancy.
-compress your data so you can store it more efficiently.
-tools that will encrypt your data when making copies.
-GUI and command line flavours

Find command can be used to copy move or delete files as we need.
>find -name "*.mp3" -exec cp {} /path/to/folder \;
This command will move all your files to a particular /path/to/folder .

Similarly you can move or delete files.
>find -name "*.mp3" -exec cp {} /path/to/USB \;
>find -name '*.mp3' -exec rm {} \;

Find files using the ownership parameter.
>find /path/to/folder -user -name “*.doc” 

Direct the output of find command to a file.
>find / -name "*.mp3" > record.txt
This command will save the paths of all mp3 files in a txt file, record.txt.

Find command demystified.

find command is cool tool for searching lost items. Lets find the mystery in 'find':

>find -name “abc.jpg”
is directory in which file is to be searched. Eg. '.' for present working directory. '/' for root [of course without single quotes].


In using wildcards * denotes the part of file you don't remember or you're not sure. Suppose your searching the file mission-impossible-3.mov. Some of the possible find searches could be:
>find -name "mission*"
>find -name "*mission*"
>find -name "*impossible*"
>find -name "mission*.mp3"
