FTP Script

tommytomato · 07-13-2006, 03:45 AM

Hi all

I've been working on a FTP script to upload some back up files onto another PC on my local network

So far so good, I get the email and the wall message and the backup file on the PC its meant to go too, but when I read my root mail I get the following message and I'm unsure what it means

Can any one let me know what it means please. Here is the email.

Quote:

mkdir: cannot create directory
`/folder/system/backup': File exists
tar: Removing leading '/' from member names
a folder
a folder/databases
a folder/html.bak
a folder/subs.bak
a folder/scripts
a folder/dbs_backup
a folder/system
a folder/system.txt
a folder/system/backup
a folder/system/backup/fullback.tar.gz: Can't add archive to itself
a folder/scripts/mysript1.sh
a folder/scripts/mysript2.sh

FTP script is here

Code:

#!/bin/bash

#Backup Script for Local Server Incremental Backups
#Broadcast Start of Backup - Uncomment Next Line
#wall A system backup is currently being performed...
mkdir /folder/system/backup
cd /folder/system/backup
#Tar files for this backup (I changed this to include tar and gz in one line.
tar -zcvf fullback.tar.gz /folder
#Mail the Administrator
#The system.txt file is what will be appended to your email. I put an
#announcement paragraph about the backup being complete.
mail username@myhost.com.au -s "FTP Backup Done" -v < /folder/system.txt
#Copy the tar file to the backup directory on the local host
#I removed the cp/rm commands here. 
#FTP the file to the backup directory on the backup server
ftp -in <<EOF

dele fullback.tar.gz
put fullback.tar.gz

EOF

You are trying to create everytime the script runs that directory

This is normal behavior of gnu tar. It means that when you'll extract the tarfile it will create the directory (folder in your case) under the current working dir and not at /. If you want to use the absolute path (i.e. extract the tarfile at /folder) use the "P" switch.

what do you mean by the "P" switch, bathory

From "man tar":

Quote:

-P, --absolute-paths
don't strip leading `/'s from file names

So if you use "tar czvfP fullback.tar.gz /folder", then using "tar zxvfP fullback.tar.gz" will extract the archive beginning from /. I think you should not use it since you can ovewrite something useful.

mkdir /folder/system/backup
cd /folder/system/backup
#Tar files for this backup (I changed this to include tar and gz in one line.
tar -zcvf fullback.tar.gz /folder

Does this thing works? Because you create an archive of a directory (/folder) in a subdirectory (/folder/system/backup), so while you're tarring and file backup.tar.gz keeps changing!!!

I took out this command all together since it was allready created once.
mkdir /folder/system/backup

the script does work, I get the wall message and the email and it uploads the file to another PC on my network ok, but I get a fcron error via root mail every hour which is tar: Removing leading '/' from member name

I'm kind of lost on what it all realy means, I spose thats why I came here to ask questions.

besides all that it was the only FTP script I could find.

Code:

 folder/system/backup/fullback.tar.gz: Can't add archive to itself

when it says that is it because it cant copy it self

tommytomato · 07-13-2006, 07:12 AM

top stuff

I fixed this error,
folder/system/backup/fullback.tar.gz: Can't add archive to itself

I created the folder out side that folder directory

just need to work out the other now "P" switch

bathory · 07-13-2006, 07:51 AM

Use

Code:

tar czvfP fullback.tar.gz /folder

to create the archive so you will get rid of the warning. But don't use "P" if you're going to extract it, since it can ovewrite things.

what you mean extract, do you mean unpack it

I would only unpack it if I needed some file to back up, say a database goes down, I would get the copy from the fullback.tar.gz file then import SQL, if you get what I'm trying to say.

It didn't like the P switch, file size was the same but the icon was different, if you get what I mean, I spose extracting it would of been acroupt file.

Yes

Quote:

That's why I suggest you to not use the "P" switch if you're going to unpack it because if you unpack the whole archive to get 1 faulty file you'll ovewrite the rest.

tommytomato · 07-13-2006, 08:24 AM

thanks for your help bathory

It makes sence not to use the P option.

Only got one error now, just wondering if I rename the folders to a folder/html.bak/
folder/subs.bak/

as in creating a folder, if you get what I mean
