In information technology, backup refers to making copies of data so that these additional copies may be used to restore the original after a data loss event. These additional copies are typically called "backups."
Backups are useful primarily for two purposes. The first is to restore a state following a disaster (called disaster recovery). The second is to restore small numbers of files after they have been accidentally deleted or corrupted.
Backup with WinRAR
Select the files you want to backup and compress them into one archive.
Choose your settings and save them in a separate profile, which you can use multiple times. Here is one example. The settings don't have to be the same as in the example.
You can modify your profile the way you want it to be: set and combine rules how to backup your files.
Add only files older or newer then ("Time")
Add only files, which are modified after a special date ("Time")
Add only files which are larger than 100 MB (command line only)
Store already compressed files (ZIP, RAR, JPG, AVI.) ("Files")
Add only files with attribute "Archive" set ("Backup")
