TAR Backup

[Terence_1]

When tar cvf /dev/rmt/0m file1 is executed form the commnand line , it does not write to
tape but file1 is emptied. Why does tar empty
a file ?

Hi,

You need to make sure that you have a
full path statement to your file or
telling the shell the current directory.

e.g.

# tar cvf /dev/rmt/0m /tmp/myfile
or
# cd /tmp
# tar cvf /dev/rmt/0m ./myfile

Hi,

tar cvf /dev/rmt/0m file1
or tar cvf /dev/rmt/0m file1 file2 file3
or tar cvf /dev/rmt/0m file*

are all valid syntaxes, pathnames are not mandatory.

I have no clue why your source file gets emptied. Did you check other possibilities ?
- tar ... > file1
- result of other process?
- emptied by other user.
...


good luck,
Thierry.
