I want to backup files from different directory ( eg. /usr , /home and /temp ) , can I use ???tar??? to backup the list of file ?

You can use tar to backup them all in a single command:

# tar -cvf /dev/rmt/0m /usr /home /tmp

In fact, you can name multiple directories in one single tar command.

You certainly can - as per the previous reply.

But remember, tar is not a very clever backup program - it does no checking to ensure your file was successfully backed up to tape. Much better to use fbackup - this is HP's recommended tool for backups as it does all sorts of error checking to ensure the integrity of your backup.

Hi,

Very much, you can use tar/cpio/dd.

If you wanted to use tar and backup on tape
#tar cvf /dev/dsk/rmtX /usr /home /tmp

or on to a file
#tar cvf file_name /usr /home /tmp

Thank your suggestion, but if I have 200 files from 50 different directories, can i specify the list in a file?

Hi,

Of course you can do this with tar, just type

tar -cvf /dev/rmt/0m /usr /home /temp .. or
tar -cvf /dir/logfile /usr /home /temp ..

But when you extract the archive it will overwrite the existing path as you use the absolute path to backup the files.

As my opinion, I like to use the relative path to backup the files, just type

cd /
tar -cvf /dev/rmt/0m ./usr ./home ./temp .. or
tar -cvf /dir/logfile ./usr ./home ./temp

When you want to extract the archive you can make a new directory first, then change directory into it and do the extract. Then you will have another copy that will not affect the original one !

Patrick

Hi.

You no need to specify all the files in a directory, just specify the directory name.
tar does the backup of all the files in that directory

Hi,

Suppose you have the list named filelist.txt

--> Start
./temp/file1
./temp/file2

..
..
./home/file2
--> End

You can just type
cd /
tar -cvf /dev/rmt/0m `cat /path/filelist.txt`

Patrick

Easy to do with fbackup, edit a file and put them in like this;

i /temp/file1
i /temp/file2
i /temp/file3
i /usr/file1
i /usr/file2
i /usr/file3
i /home/file1
i /home/file2
i /home/file3

Then use the command;
fbackup -v -f /dev/rmt/0m -g
