Using slapconfig -backupdb in a backup script

[kainewynd2]

First item to note: I am competent with bash scripting, but not “good.” If I was good I wouldn’t be asking this question. 🙂

So, I have a client who was only able to purchase one OD Xserve to use in a AD-OD integration project. Everything is running great (finally), but I would like to be able to pull nightly database backups since we don’t have a replica scenario in place.

So far I have the following:

[code]
############################################
# VARIABLES
############################################
DATE=`date “+%Y-%m-%d”`
BPATH=”/Volumes/Data/Backup/ODBackup”
FILENAME=”$BPATH/$DATE-backup”
PASSWORD=”blargh”

############################################
# WORK
############################################
/usr/sbin/slapconfig -backupdb $FILENAME

/usr/sbin/chmod 700 $FILENAME
[/code]

As you can see I am missing one major portion of the code which is where I pass the archive password variable. I know this sort of thing is possible in bash scripting, but I’m not entirely sure what it’s called so I haven’t had any luck looking it up.

Additionally, I am aware of the security implications of having the archive password in a clear text document and will have permissions set accordingly.

Thanks in advance.

That would be the “expect” command which works interactively with the current tty. Have a look at Andrina’s article on changing local admin passwords (it’s a few years old, but a good illustration on how to use expect).

For the record, my [i]expect[/i] script is as follows (based on the suggestion [url=https://www.afp548.com/comment.php?mode=view&cid=6405]here[/url]):

[code]#!/usr/bin/expect -f

set date [timestamp -format “%Y-%m-%d”]
set archive_path “path/to/you/backup/dir”
set archive_password “password”
set archive_name “opendirectory_backup”

spawn /usr/sbin/slapconfig -backupdb $archive_path/$archive_name-$date
expect “Enter archive password”
send “$archive_password\r”
expect eof[/code]

Hope that helps others since I’ve not seen one like this actually posted anywhere. I really do wish the [url=https://www.afp548.com/article.php?story=20050622155757690]serveradmin method[/url] worked for me though.

[b]Edit:[/b] Of course, you really want to run put this file in root’s crontab so it runs nightly and also change the permissions to r/w/x for root-only as you’ll be storing the password right in the file.

Thanks! This worked great.
