Title: Persistence fails
Post by: hypersonic on October 19, 2011, 05:15:46 PM

Ok. I've installed Tiny Core on USB. I just lost all my backup, simply by restarting the computer. The first few times it happened, I thought it was just some wrong configuration. This should happen?

Funny, this time my .filetool.sh is intact... Here is my .filetool.sh:

# tiny core persistence
opt
# xorg persistence
etc/X11/xorg.conf
# root password persistence
etc/passwd
etc/shadow
etc/gshadow
# rails persistence
usr/local/lib/ruby
usr/local/bin
usr/local/bin/install
# fluxbox persistence
usr/local/share/fluxbox/styles/darkmatter

So: opt, usr/local/bin, usr/local/bin/install and usr/local/share/fluxbox/styles/darkmatter was totally restored. File /usr/local/lib/ruby was partially restored (miss site_ruby file). And the rest was not recovered.

.filetool.sh is meaningless.
The file should be .filetool.lst and it cannot contain comments.

Ops, its .filetool.lst... sorry. I removed comments, and I found a solution for another post. I suspected that this problem (about persistence) could be caused by backup files size (around 200 MB unpacked). Then by chance I found this wiki page: http://wiki.tinycorelinux.net/wiki:extension_for_settings (http://wiki.tinycorelinux.net/wiki:extension_for_settings), and created an extension TCZ for ruby folder. So I really don't know if this problem is caused by backup size or the comments...

If help someone, I put how I did a TCZ extension of ruby file on this post: http://forum.tinycorelinux.net/index.php/topic,11656.0.html (http://forum.tinycorelinux.net/index.php/topic,11656.0.html)

I was having this problem of backup loss before use comments in filetool.lst...

You have other problems with your .filetool.lst.
opt should not be included as a directory.
You have directories and their subdirectories included.
You are not running a standard configuration, as you have not included home.

You probably had errors in it then too.

I don't see any errors beside that I've related, but thanks for the tip. Home is not included on .filetool.lst because its already persistent by extlinux.conf

That's your problem. You don't see the errors even after they are pointed out to you.

I've seen the error in .filetool.lst, again, thanks for the tips. What I meant was that I did not see any errors that may compromise my normal use of the system. I'm no longer posting on this forum. Thanks all for everything

opt in .filetool.lst will cause you many problems, as a restore will overwrite dynamic system information.
You must list each individual file in /opt that you wish to backup.

Hi hypersonic
You probably should not be backing up  /usr/local/bin. Any special reason you added that?

Since when are you supposed to put home in backup?

Title: Re: Persistence fails
Post by: Rich on October 20, 2011, 08:28:26 AM

Hi hiro
If you have a non-persistent home, it should be in backup. In hypersonic's case, based on what
he wrote in another thread, he shouldn't.

Title: Re: Persistence fails

I'm asking because I used to only put specific files/folders from my home folder in backup so that I don't have too much work putting all the others in .xfiletool.

Title: Re: Persistence fails

Hi hiro
The stock  .filetool.lst  has  home  included  and  .xfiletool.lst  contains certain exemptions. This
serves as a good starting point for new users with a non-persistent  home  which then can be
modified to suit ones needs.

Please do a man on the tar command. Specifcally the -T option and the -X option.
You can even use google, bing, duck duck go, yahoo. It is not rocket science. It is not unique to Tiny Core.

Hint.  -T uses /opt/.filetool.lst   -X uses /opt/.xfiletool.lst

Simple basic file managment. Static content should not be included in backup but should be a candidate for a personal extension or stored on other persistent store.

This procedure has been in public use for 8 years across two distributions and is covered in the Core Concepts document.

Persistent does not fail unless caused by user error in not understanding the basics involved.

Ok, I thought not having home in .filetool was "unsupported" when I read the sentence "That's your problem.". I'm happy to see this is not the case.
