Puppet users - Nov 2009 - Simple script for restoring puppet hosted files from local backup

Hi.

I found this script to retrieve backed up puppet hosted files:
http://markmail.org/message/nybqh3be7bcge33h

..and made some adjustsments. I''ve pasted the script below in case
anyone
else are in need of such a script:

--- snip ---
 #!/bin/bash
file=$1
BUCKETDIR=$( puppetd --configprint clientbucketdir )
PREFIX="* "
entries_found=0
echo "Searching for local backups of file $file (this may take some
time)..."
for f in $( find $BUCKETDIR -type f -name paths -exec grep -l $file {} \;
|xargs -r ls -t);
do
  md5sum=$( basename $(dirname $f))
  filename=$(< $f )
  modify_time=$(stat --format ''%y'' $f)
  echo -e "$filename\t$md5sum\t$modify_time"
  entries_found=1
done
if [ $entries_found -eq 1 ]; then
    echo ""
    echo "Horray, backup(s) were found!"
    echo "* To view the contents of the file, issue this command:
\"filebucket -b /var/lib/puppet/clientbucket get
<md5sum>\""
    echo "* To restore the file, issue this command: \"filebucket
restore -b
/var/lib/puppet/clientbucket /path/to/new/file <md5sum>\""
else
  echo "No entries were found. Exiting."
--- snip ---

Note that the script retrieves files only from the local backup directory. I
added the "-r" argument to xargs so that the loop structure would not
run
unless the "find" command actually find a match. Without the
"-r" switch,
the loop would run even if you pasted a invalid file name, which for me
caused unexpected results.

Kenneth

Note that there''s a ''filebucket'' script that is
actually in the bin
directory in the Puppet repo.
