About ext3 FS

Hi There,

I just wonder things about ext3.. I mean I really want to use/know all benefits of using ext3 on my system. My fstab is like this:

[12:25] (tunix@penguix ~)$ cat /etc/fstab
# 
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0

/dev/hda4              swap          swap      defaults            0      0
/dev/hda3              /             ext3      defaults            0      0
/dev/hda2              /pub          vfat      defaults,umask=0002,gid=users 0 0
/dev/hdc               /media/cdrom  auto      auto,rw,user        0      0
/dev/sr0               /media/dvd    auto      auto,rw,user        0      0

What things should I know about my ext3 file system ? Should the dump and pass numbers important ? What should I change if necessary ?

Although how can I recover files if I loose data ?

man fstab. The dump field seems to offer some way of having the filesystem dumped somewhere, possibly a backup mechanism. I've never seen it used.

The pass sets whether or not the filesystem will be fsck'ed on bootup. Many people turn this off, I leave it on just in case. The manpage recommends a value of 1 for /, and 2 for the others.

Don't lose data. Backup. ext3 is pretty safe, but like hard drives -- it's man made.
