My advice : Use secure ftp (SSH) http://www.openssh.org ( easy, quick, secure ) and there is free software client for winbug if you need it like this: ftp://ftp.ssh.com/pub/ssh/SSHSecureShellClient-3.2.9.exe but..... If your users are changing the same files, then you need CVS.- I dont like samba. -- Jota Omella http://developers.com.py

Everything must be done via perl. I have already download vsftp for trasferring the files (Net::FTP) BUt is it a good idea to store gifs (~100 Kb) in a Mysql database or to store the images in the file system directly? ----- Original Message ----- From: "Javier Omella" To: Sent: Sunday, February 22, 2004 5:32 PM Subject: Re: [SLE] File Server

I don´t think it is a good idea, some guys maybe think is ok but in my personal experience is more slow and you have much development, and in the future if for some reason you are adding more weight images, your system will be even more slow. Maybe in DB like Oracle or M$SQL with store procedures!! Security? yes, it is more secure in the DB, but, it´s just question of doing things right Maybe someone here have a different experience than me, and can share it. cheers.

Even in Oracle this is a really bad idea. I know because I had this conversation with someone who is an Oracle DBA last week about it. You store the links to the images (/var/spool/pictures/winter/p001.jpg) before you store the body in the database. This way you can do a few things with the database. Back up is easier because you don't have to manage a binary block of data that never changes. You can visually verify that the images called are the images seen. You can do debugging more easily by keeping the images in a space that is readily accessable for you to look at. Putting it into a database gaurantees that you will never be able to debug it without building a bunch of software to pull the image out of the database for you, but that software has to be 100% bug free...

Well, storing the to file system it sounds much better. But how could a backup be done? I mean automating the backup process via a script.

Thank you for you response! Now the most critical question! Which File System? I have experienced many errors concerning uncleaned reboots and then the disaster comes. What do you suggest?

Same place you would back up the database. tape drive or disk would be my guess. Or CD-ROM

Not at all. I've got a weekly cron job which calls a script that does a dump of the mySQL database containing all my recipes to a directory where I keep other files that I want to back up regularly, then calls mkisofs and cdrecord to create and burn an image to CD-RW.

There's a package, called cdbkup ... not on SuSE but available in the community that does incrimental, differential and full backup to CD-ROMs.
