This =>works well, but takes up a lot of space, and only two days worth of =>archives fit on a single CD. I know how I want to remedy the situation, =>but I don't know how to script it. Here's what I want to do: On Sunday =>I want the whole /home folder backed up into its own file. On Monday =>through Saturday I want only the files that have changed since the last =>backup backed up into their own files, one for each day. That should =>make seven files that are small enough to fit onto one CD. One CD per =>week. Is it possible to do it this way, and if so, how would I do it? =>I do a lot of programming, so I need separate backup archives so that I =>can access an older version of a particular file if need be... See the info pages on tar. Look at the Incremental options. `--incremental' (`-G') is used in conjunction with `--create' (`-c'), `--extract' (`--get', `-x') or `--list' (`-t') when backing up and restoring file systems. An archive cannot be extracted or listed with the `--incremental' (`-G') option specified unless it was created with the option specified. This option should only be used by a script, not by the user, and is usually disregarded in favor of `--listed-incremental=SNAPSHOT-FILE' (`-g SNAPSHOT-FILE'), which is described below. -- Time flies like the wind.
