 |
|
I'm trying to make a shelld script that would backup my /home /var /usr dir's to a tar file. I tried this simple command tar -cZf /root/backup/backup.tgz /home/ and i get this error
tar: Removing leading `/' from member names
tar (child): compress: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
Broken pipe
any idea on what do here? Also anyone already have a good script i could use to do this ?

| Code: | | tar jcf /usr/local/backup/backup.tbz2 /home |
worked fine to me. I still got the error about removing the leading '/', but everything was backed up. Maybe compress just can't handle what you're trying to do. Try archiving it with either gzip (-z) or bzip2 (-j) instead (better compression anyway. |

For tar:
Z = compress (Unix compress program that has potential patent encumberances)
z = gzip
j = bzip2
You don't have compress installed. bzip2 should generally give you better compression that gzip. |

I was thinking along those lines from the error msg but you never know. So I used gzip  next time ill try bzip2
