Storage devices are not 100% failsafe, and one should maintain multiple archives on separate devices. It may also be prudent to maintain inetrmediate versions of a base, allowing fallback to an earlier version in case of severe modification problems. Lastly, the .gw save format is a clean and sure mechanism to exchange bases between GeneWeb users (GEDCOM is also available but not with 100% compatibility).
A simple mechanism to archive a base is to make a copy of the base.gwb folder. A better mechanism is to produce a textual base.gw file using the .gw format.
To create an archive for base
toto, use the gwu command and archive the resulting output:
gwu toto > toto.gw
Or using option -o for gwu :
gwu toto -o toto.gw
You may select any name of your choice, provided you keep the extension
.gw. For safe archival, make multiple copies of the base.gw file, on multiple devices.
Using the ;gw file format has many avantages :
- simpliciy : a single file when the base folder contains multiple files (note forum and update history are not preserved through a .gw file) ;
- economy : a .gw source file is quite smaller that the corresponding folder ;
- compatibiliy : the .gw format maintains compatibility with future versions of GeneWeb ;
- accessibiliy : the .gw is a human readable format, and allows for global editing or difference detection (using a command such as
diff base-v1.gw base-v2.gwunder Unix/Linux/OSX)
To restaure base
toto.gw, use the gwc commande:
gwc toto.gw -o toto
