Subject description: Backup your live save file		  
A tiny gtkdialog utility for backing up the live pupsave file. You no longer need to reboot with pfix=ram in order to backup the savefile. Lots of built-ins and safety features make it very "oops" proof.

Auto-detects the current savefile.
Generates the backup file name with the date and time appended.
Checks the available space for the backup file.
Will not perform the backup if anything is incorrect.
Displays real-time status and progress feedback.
Supports 2fs and 3fs save file types.

It's easy fast and works very well.

What can I say 2byte, but simple, small, clean, wonderful. Puppy has needed just such a utility for a very long time. Really very well done.

One suggestion. Gzip the backup. That'll squeeze the air out of it Wink.

Thank you very much!

Very nice gui for copying a "hot" file - But, some caution is in order.

The filesystem may be writing when you do this and problems can happen. Here's some further explanation of what to watch out for....

The only surefire method to make and verify an exact copy is to not try copying a mounted image - i.e. using pfix=ram instead.

Thanks for the compliments, I hope it serves you well.

Yeah, deleting all of my code comments would knock a chunk out of it too Smile

@seaside
Caution noted. Common sense applies here. As noted in the help dialog, shut down all of your apps before running the backup. I have been backing up in just this manner for about a year now using a hard coded script without any problems whatsoever. Also the utility runs e2fsck on the backup as a safety measure and doesn't need pfix=fsck on the next boot.

Speaking from experience, installing software or trying a new version of Puppy is much more dangerous to your savefile. Wink

Perhaps you misunderstood me. I refer to compressing the newly backed pup_save file, not your code. Pup_save's are "sparse" files whose free space is highly compressible.
