tar -p parameter error

Hi

When i try to backup using this:
tar -zcfp /home/backup/forumfiles_$(/bin/date +%Y-%m-%d).tgz public

---

i am getting this error:
/home/backup/forumfiles_2014-10-10.tgz: Cannot stat: No such file or directory

and when i remove the p from parameters is fine but i want to get backups using p (preserve permissions)
Any ideas how can i fix this?

Thanks

 

Ok thanks

 

Is there anyway to create a folder using the date (/bin/date +%d-%m-%Y) and add there all backups from databases and forum files?

So i can get :

/backup/22-10-2014/databases and files here from that day
/backup/23-10-2014/databases and files here from that day


#!/bin/bash
# Edit the variables below
DBNAME="name_db"
DBUSER="user_db"
DBPASSWD="123456789"
BACKUPDIR="/backup"
PUBLICFOLDER="/home/nginx/domains/mydomain.com"
/usr/bin/mysqldump $DBNAME -u $DBUSER -p$DBPASSWD > $BACKUPDIR/database.sql
cd $BACKUPDIR
/bin/tar -zcf database_$(/bin/date +%d-%m-%Y).tgz database.sql
cd $PUBLICFOLDER
/bin/tar -cpvzf $BACKUPDIR/sitefiles_$(/bin/date +%d-%m-%Y).tgz public
sleep 2
rm $BACKUPDIR/database.sql

How can i do this please?

Thanks

 

Ok thanks i will try it

 

Also in the net the most scripts start like:

#/bin/bash
and not like mine:
#!/bin/bash
is this a problem?

 

I found the answer for the above so ignore it

 

Ok thanks

Can you recommend me if i must use the sleep command in any other place to avoid any problems?

Also is there any specific reason to use verbose on a bash script -v as you recommend me?

tar -cpvzf

Thanks
