Archive - An archive is a reserved location for a group of files with the intent to preserve the information in those files. Files that make up archives are often stored in what is called a "ZIP" file. A "ZIP" file is a file that contains other files that are compressed to preserve space. Zip archives are convenient for containing files that you want to preserve as backups or as a convenient way of sending multiple files to someone.
Automatic Archive - An automatic archive is an archive that is done for you with out you having to initiate it or decide which files get archived.
Backup -In a nutshell, a backup is a duplicate copy of a file or document kept in case the original is lost or corrupted. There are different types of backups.
Local Backup - Is a copy of a file or document that is located on the computers hard disk drive. This type of backup provides a minimal guard of ensuring that you have a way to restore your data. This minimal level of safe guard is because if something causes your hard disk drive to fail in your PC, or corrupts your data, you may loose the backup copy also.File Extracting - Is the process of removing files from an archive (ZIP) file. This "remove" is a non-destructive move. (i.e. a copy of the files still exists in the archive).
Remote Backup - Is a copy of a file or document that is NOT located on the computers hard disk drive. It is typically located on a removable media like a floppy disk or other removable media, or a network drive (on a server or different computer). This type of backup provides a good level of safe guard of ensuring that you have a way to restore your data. This increased level of safe guard is because if something causes your hard disk drive to fail in your PC, or corrupts your data, you have a copy of your information located elsewhere.
Off Site Backup - Is a copy of a file or document that is located in a location other than physical building that your PC is. It is typically a copy on removable media that is physically transported to a different geographical location, like a different office, safe deposit box, or a friends house. This increased level of safe guard is because if the building where your PC is burns down or is robbed you have another copy located in a different building. The chances of both locations burning down is unlikely. You may think this is off site backup is going too far, but if you have put years of work into something it can be well worth an off site backup.
Note: It is a good idea to keep old backups. The older copies provide a history reference that can be helpful. And, if something is wrong about a recent backup, you will have an older copy to go back to.
File Types - A file type refers to the type of information that a file contains (i.e. document, spread sheet, data base, picture ...). To identify a file as a particular type, the computer uses a file extension. A file extension consists of the characters after the '.' such as ".doc", ".txt", ".xls", ".bmp"...
Self extracting Archive - A self extracting archive is an archive where you do not need a program, such as the File Archiver, to extract the files contained within the archive. A self extracting archive typically has a small program contained within the archive that allows the files to be extracted. A self extracting archive typically is an .EXE file. Using a self extracting archive is useful to send archived files to someone that does not have an archiving program.
Zip file - A file that contains other
that are compressed to preserve space. Zip archives are
for containing files that you want to preserve as backups or as a
way of sending multiple files to someone. It is a very common format
an archive to be in.
