what is wrong with my server backup script ?
 

Please help. I am new to linux. I wrote a script to run the backup on lunix machine but the job gave me an error. I am using Linux 2.6.14.3. Below is the sample of my script can anyone tell me where went wrong? Thanks in advance.

#!/bin/sh

dat=$(date +%d%b%y)
logdir="/usr/local/scripts/log/backup"
backuptarget="/*"
backupdir="/usr/hell/backups"

for HOST in devil1 devil2 devil3
do

ssh $HOST "tar -zcvpf $backupdir/$HOST.$dat.tgz $backuptarget --exclude "/usr/hell/DB" >> $backupdir/$HOST.backup.log.$dat "

ssh $HOST "cat $backupdir/$HOST.backup.log.$dat" >> $logdir/"$HOST.backup.log.$dat"
gzip $logdir/"$HOST.backup.log.$dat"

scp root@$HOST:$backupdir/$HOST.$dat.tgz $backupdir

# scp exits with 0 on success or >0 if an error occurred.

if [ $? -gt 0 ]; then
/var/netpage OPERATIONS -TSMS -G10.200.1.99 "$HOST scp failed"
fi

/bin/tar ztvf $backupdir/$HOST.$dat.tgz ||/var/netpage OPERATIONS -TSMS -G10.201.2.66 "$HOST.$dat.tgz is no good"

ssh $HOST "rm -f $backupdir/*"

done


/bin/tar -zcvpf $backupdir/devil1.$dat.tgz /* --exclude "/usr/hell/backups/*" --exclude "/usr/hell/DB/*" --exclude "/usr/dragon/.cache/*" >> $logdir/"devil1.backup.log.$dat"

gzip $logdir/"devil1.backup.log.$dat"

/bin/tar ztvf $backupdir/devil1.$dat.tgz ||/var/netpage OPERATIONS -TSMS -G10.200.1.99 "devil1.$dat.tgz is no good"

#zip up /usr/hell/backups directory as windows bkf file is big
gzip $backupdir/*

/bin/tar -rvpf /dev/st0 $backupdir/* /usr/hell/DB/200[4-6]*/* --exclude "*log*" >> $logdir/"tape.backup.log.$dat"
/bin/gzip $logdir/"tape.backup.log.$dat"
rm -f $backupdir/*

What's the error?

This looks like a script you got somewhere on the internet. I'm assuming you've edited this script to suite your environment? For example, you must fill in appropriate host names, directory names, etc.

The below is the error message

"$HOST scp failed"
"$HOST.$dat.tgz is no good"
