Re: script to restore all the files and selected files in tar format

Hi:

To restore from your tar archive, do something like:

# tar -xvf myarchive

...or for individual file(s):

# tar -xvf myarchive file1 file2 file3

Regards!

School assignment? Perhaps you should post
the actual requirements.

> i am attaching my backup script [...]

Interesting. I like the way it creates a
".tgz" file, but where does it do any gzip
compression? Doing an "rm", even if the
previous "tar" command failed, may be unwise.

What, exactly, do you think that this does?
Have you tried any of this stuff? (By the
way, should we non-psychics know what "$2",
"$3", and "$6" are in this case?)

> #creates backups of essential files

Probably not entirely true.

If you were depending on _this_ script for
your back-up operations, then you would seem
to be kidding yourself.

You just do the reverse of your backup script:
# restore from weekly a full backup of all data and config. settings:
tar xf /export/data/data_full_$6-$2-$3.tgz

Note: you haven't gzipped that tar file.

tar xf /export/config/config_full_$6-$2-$3.tgz

# restore from incremental backup:
tar xf /export/data/data_diff_$6-$2-$3.tgz
tar xf /export/config/config_diff_$6-$2-$3.tgz

>abir: #tar -xvf /*

This "/*" isn't going to work unless the system has the exact files on the tape. AND you forgot the tarfile:
tar -xf foo.tar
