Re: [Jed-users-l] extended backup (versioning)?

[Ulli Horlacher <framstag@xxxxxxxxxxxxxxxxxxxx>]

Is anyone still reading with me or do I talk to myself only? :-)

My users disliked the file mess :-}

So I moved the versions to an own subdirectory and integrated the normal
backup file~ into the file versioning.

Now it looks (after some editing/saving):

framstag@fex:/sw/share/jedlib-0.99-19/lib: ll versions.sl* .versions/vers*
-rw-r--r-- framstag users    2,050 2013-04-13 11:59:22 versions.sl
-rw-r--r-- framstag users    2,031 2013-04-13 11:56:41 .versions/versions.sl~1~
-rw-r--r-- framstag users    1,953 2013-04-13 11:39:43 .versions/versions.sl~2~
-rw-r--r-- framstag users    1,774 2013-04-13 10:09:06 .versions/versions.sl~3~
-rw-r--r-- framstag users    1,822 2013-04-13 10:01:55 .versions/versions.sl~4~
-rw-r--r-- framstag users    1,854 2013-04-13 09:58:03 .versions/versions.sl~5~
-rw-r--r-- framstag users    1,855 2013-04-13 09:57:25 .versions/versions.sl~6~
-rw-r--r-- framstag users    1,854 2013-04-13 09:33:51 .versions/versions.sl~7~
-rw-r--r-- framstag users    1,664 2013-04-13 09:03:53 .versions/versions.sl~8~
-rw-r--r-- framstag users    1,664 2013-04-13 09:03:05 .versions/versions.sl~9~


So, in the normal directory you see no more any backup or version files.
This is much cleaner.
But you have access to the last 9 versions of your edited file.

It is little bit like what Netapp does with WAFL .snapshot/
