Backing up one file in volume


Recommended Posts

There are two answers. Both will work, it's just a matter of how long it takes. One is MUCH faster than the other.

 

(1) An answer to your question that works, but that takes a long time:

 

Define a Selector to choose only that "one file", make a script to back up the "particular volume" that holds that "one file", put that Selector in your script to define what is being backed up. I would point you to the exact page in the Retrospect Users Guide where this is discussed, but you haven't provided any information about your version of Retrospect, so I can't point you to the right manual. The documentation is here:

Retrospect documentation

 

(2) An answer to your question that works, but which is very fast:

 

Define a Retrospect "subvolume" as the directory that holds the "one file". Define a Selector (see above) to choose that one file's name. Make a script with that subvolume as the source, use that Selector to choose what files are backed up (only that one file).

 

What is happening is that, by Retrospect's design (the reasons are complex, and it isn't my design), it first constructs a list of files to back up by scanning the entire source volume, even if only a single file is to be backed up, and then passes that list through the Selector conditions to filter out the files that will actually be backed up.

 

By defining a "subvolume", Retrospect only scans that directory and everything in the filesystem tree below that directory, so you cut out the scanning of the rest of the volume.

 

Clear?
