rsync-backup Revisited

2010-07-19T17:43:00.003-04:00

In light of a recent comment on my rsync backup script, I thought I would post the updates that I have made to that script. The highlights include remounting the backup filesystem as read-write just before copying and then remounting it as read-only afterwards. This features allows for more security, you cannot change your backups after they happen. Secondly, I added a quick stats file that tells you the size of each increments folder. This file is a great way to easily tell which folders to delete when you are running low on disk space.

The scripts may be found on GitHub at http://github.com/jag3773/rsync-backup.

Hebrew Reading Ease Comparison

2010-07-19T13:07:00.004-04:00

I've created a quick comparison of Genesis 22 and Genesis 37 via the Hebrew Reading Ease scale. The results are interesting, here is the comparison. Follow this link to learn more about the Hebrew Reading Ease scale.

Basics of Biblical Hebrew Vocabulary

2010-05-29T09:24:00.001-04:00

I added all of the Hebrew vocab for Basics of Biblical Hebrew by chapter into Quisition. The original announcement is on http://www.ekfocus.com. Hopefully this will prove helpful for Hebrew students this summer and beyond ;)

Exegetical and Hermeneutical Terms

2010-03-10T10:09:00.003-05:00

If anyone is looking to memorize common exegetical terms and/or common hermeneutical fallacies, I've added many of them into www.quisition.com. They are taken from the appendices of the book Old Testament Exegesis, by Douglas Stuart.

You can view them by clicking here: http://www.quisition.com/packs/?search=Old+Testament+Exegesis&results=10&sort=popularity

Aramaic Vocab

2010-01-29T13:56:00.001-05:00

I'm currently in the process of adding Aramaic vocabulary into Quisition based on Alger F. Johns' A Short Grammar of Biblical Aramaic. If you would like to follow the progress and/or start learning the vocab then click this link: http://www.quisition.com/packs/?search=aramaic&results=21&sort=popularity.

A Holiday Prayer

2009-12-01T05:04:00.000-05:00

Lord God,
Thank you for the joy inherent in this wonderful season which distinctly celebrates Thanksgiving, the birth of Jesus Christ, and new beginnings, signified by these and in the New Year. Let us not forget the source and reason for this joy. Let us not gaze into the bright lights of Christmas without looking through them to the bright Light who is your Son. We cannot know you except that you reached down and became one of us. This we celebrate. This is where the joy of Christmas comes from. This is why we give Thanks. Lord, this is why we can confidently look forward to the new beginning of of your Kingdom.

We love you Lord. Amen

Time To Read

2009-08-10T11:30:00.003-04:00

I may not be much for blogging in the coming months. I'm sure I'll sneak one in from time to time but don't count on it. I've got a lot reading and studying ahead of me. I will be more active at EKFocus.

Hebrew Transliteration and Pronominal Suffixes

2009-07-18T11:45:00.005-04:00

I have now added into Quisition two new Hebrew vocab packs. The first is Hebrew letters with their transliterated values. This will serve anyone that needs to read scholarly literature which often uses transliterated values for the Hebrew letters. The second pack is the pronominal suffixes which occur on nouns, prepositions, and the definite direct object marker. These suffixes are also very similar to the ones that appear on Hebrew verbs, thus, learning this set is doubly helpful.

I think this is the last of the Hebrew vocab packs that I plan on adding to Quisition for a little while. Next up is Aramaic!

More Help with Hebrew

2009-07-13T20:48:00.002-04:00

If you have trouble nailing down Hebrew Independent Personal Pronouns and Hebrew Demonstrative Pronouns then head over to Quisition.

Pronominal suffixes are on their way!

2009-07-08T09:10:00.003-04:00

I can't believe that it is finally here! Google has just announced Google Chrome OS. Everyone knew that this was inevitable but now it has finally occurred. Very soon it looks like this will be available.

Very exciting times. One more reason for my child to one day ask, "Now, who was Microsoft again?"

Gmail Comes of Age

2009-07-07T12:12:00.003-04:00

Finally, Gmail, Google Docs, Google Calendar, and Google Talk are officially released. All this really means is that the familiar "BETA" tag that was underneath each of the respective icons will be removed today. When I first checked my email it was still there, however, I logged out, refreshed the page, and logged in again only to find that I'm BETA free!

The software hasn't changed any more than it did yesterday or 2 weeks ago. The real key is that Gmail is a web app that is always evolving. Likely, new features will continue to be introduced via the Labs feature and then slowly, if successful, moved into the final applicaiton for all to use.

Here's to Gmail!

Hebrew Vocab at Quisition

2009-07-02T15:10:00.003-04:00

I've now been able to enter in all words in the Hebrew Bible that occur more than 50 times but less than 139 times. I've got down as low as I plan on going for a while but I'm still working on the higher numbers. I plan on having all of the words occurring more than 50 times entered in by the fall. Perhaps this will serve as an aid to first year Hebrew students beginning their study in Fall 2009. I've got about 292 more words to add in to accomplish that, definitely tenable by the fall.

I would also like to add in some different types of cards. I found it helpful for me to memorize pronominal suffixes, relative pronouns, personal pronouns, numbers, and even the verb paradigms with vocab cards. Ideally, those will be entered in sometime soon as well.

I've got an itch to start adding in Aramaic as I will be taking that in the Spring of 2010. If I have them all added in beforehand then I'll benefit from the site's intelligence as I set out to learn yet another Semitic language!

Follow my progress in adding in Hebrew vocab cards.

Quisition

2009-06-23T16:48:00.004-04:00

Quisition is wonderful. The site allows anyone to create vocabulary cards with anything on either side of the card and then allows everyone else to use those cards. Thus, if you want to learn Biblical Greek vocabulary or Biblical Hebrew vocabulary while at the same time memorizing simple addition, then Quistion is the site for you. The best part is that the software is smart, it keeps track of which cards you've got right and which ones you've missed so that it can quiz you appropriately.

I'm currently working on adding in Biblical Hebrew according to word frequency. Right now I've got the middle section of words added in. Basically, I'm memorizing down to 50x this summer so by August Hebrew vocab should be entered in from about 120x down to 50x word occurences.

Language Instruction

2009-05-26T06:01:00.000-04:00

Here is a link to a four part series discussing classical language instruction: http://jeltzz.blogspot.com/2009/05/conversational-dead-languages-i.html

All in all I tend to agree with author. One of my largest frustrations with my language instruction is that so little of it has been devoted to helping me learn to read the texts. I've longed for a professor that would require us to read the text, not just a verse or two, but large chunks of the text. I've finally come to an independent study course that will allow me to head down that road with Hebrew. Thus far, it has been a joyous, albeit time-consuming, experience!

Historical Exegesis

2009-05-25T05:26:00.000-04:00

"The Bible is such a historically oriented revelation that ignoring historical context tends to assure misinterpretation."

Erasmus on Grammar

2009-05-23T12:22:00.002-04:00

"Nor do I assume that theology, the very queen of all disciplines, will think it beneath her dignity if her handmaiden, grammar, offers her help and the required service. For even if grammar is somewhat lower in dignity than other disciples, there is no other more necessary. She busies herself with the very small questions, without which no one progresses to the large. She argues about trifles which lead to serious matters. If they answer that theology is too important to be limited by grammatical rules and that this whole affair of exegeting depends on the Holy Spirit, then this is indeed a new honor for the theologian that he alone is allowed to speak like a barbarian. Shall we now attribute our errors to the Holy Spirit?"

Erasmus, Preface to Valla's Annotations on the New Testament

Good Application in Exegesis

2009-05-18T04:57:00.000-04:00

"Subjectivity is the primary enemy of good application. When people think that they can derive from a passage an application somehow relevant to them but not to others, or somehow unique to one passage but not even comparable to the applications of genuinely similar passages, the probability of logical consistency is reduced and the likelihood of accuracy is threatened."

Stuart, Douglas, Old Testament Exegesis (Louisville, KY: Westminster John Knox, 2009), 26.

Searching for Exegesis

2009-05-15T16:50:00.004-04:00

"The more of these sorts of works you have via computer software, including online access, the faster your exegesis work can go because of the time saved in searching. On the other hand, speed is not always an advantage: searching through a book forces you to see things in context in a way that searching via search engines prevents you from doing."

Stuart, Douglas, Old Testament Exegesis (Louisville, KY: Westminster John Knox, 2009), 3.

rsync Home Backup Script

2009-05-11T21:52:00.006-04:00

I recently had trouble with a very good backup utility, rdiff-backup. I have always liked its functionality and it usually worked very well for me. However, I ran in to some trouble and somehow my backup information got corrupted, which kept the program from completing subsequent backups. This is not good. Because it was a bit of an obscure program and because I realized that I was using a program that I couldn't very easily dissect and because I was afraid that my actual data may become corrupt I decided to switch to another backup utility.

The process of searching for another backup utility turned south when I realized that there wasn't really any that did what I wanted. Here is all I wanted:

Backup my /home/jkag/ directory, except all of the hidden files (.*)
Keep incremental changes in an easy to get to location so that I could hand restore them as needed
Be executable via cron
Something written in Python would have been nice, but really, whatever worked would have been fine
Keep a simple and easy to read log of everything that happened during the backup run

To me, this sounded like a pretty basic set of requirements for running backups. In fact, I figured everyone else (who is running Linux) would be doing the same thing. Yet, I was wrong, I found it very difficult to find a program that worked to my liking. I did look at http://www.diffingo.com/oss/fwbackups but that turned in to something much more complicated than I desired (installation in particular).

All of this history to say that I decided it would be easier to write my own backup script. I had done this several times in Windows, using xcopy. I knew that it would be fairly simple to write a bash script, utilizing rsync, to do all of this. So that's what I did, here it is!

#! /bin/bash

#Variables
BACKUPTIME="`date +%m-%d-%Y`"
SOURCEDIR="/home/jkag/"
BACKUPDIR="/opt/Backup/jkag"
LOGDIR="/opt/Backup/rsync-backup.log"
INCREMENTSDIR="/opt/Backup/jkag-increments/$BACKUPTIME"
MYTITLE="================================="
MYSUBTITLE="------------------"

#Log formatting
echo $MYTITLE >> $LOGDIR
echo $BACKUPTIME >> $LOGDIR
echo $MYTITLE >> $LOGDIR
echo "BEGIN BACKUP" >> $LOGDIR
echo $MYSUBTITLE >> $LOGDIR
echo >> $LOGDIR

#This script syncronizes the home directory with the backup directory and puts backups of changed and deleted files into a folder with the current date in the jkag-increments directory
mkdir $INCREMENTSDIR
rsync -avb --delete --exclude ".*" --backup-dir=$INCREMENTSDIR $SOURCEDIR $BACKUPDIR >> $LOGDIR

#Log formatting
echo >> $LOGDIR
echo "END BACKUP" >> $LOGDIR
echo $MYSUBTITLE >> $LOGDIR
echo >> $LOGDIR
echo >> $LOGDIR

However, the whole time I knew that I would really rather be writing this script in Python. So, after I wrote it out and tested it in bash I went ahead and rewrote it in Python. This was a lot of fun! Here are the Python scripts.

rsync-backup.py

#!/usr/bin/env python

#This script syncronizes the home directory with the backup directory and puts backups of changed and deleted files into a folder with the current date in the jkag-increments directory
import os
from time import asctime
import restformat

#Variables
backupruntime = asctime()
sourcedir = "/home/jkag/"
backupdir = "/opt/Backup/jkag"
incrementsdir = '/opt/Backup/jkag-increments/' + backupruntime

#Logging
backuplog = open('/opt/Backup/rsync-backup.py.log', 'a')
print >> backuplog, (restformat.title(backupruntime))
print >> backuplog, ('Making increments directory: "' + incrementsdir + '"\n')

#Make incrementsdir
os.mkdir(incrementsdir)

#Logging
print >> backuplog, (restformat.subtitle('BEGIN BACKUP'))
backuplog.close()

#Run rsync backup command with Linux logging
os.system('rsync -avb --delete --exclude ".*" --backup-dir=' + '"' + incrementsdir + '" ' + sourcedir + ' ' + backupdir + ' >> ' + '/opt/Backup/rsync-backup.py.log')

#Logging
backuplog = open('/opt/Backup/rsync-backup.py.log', 'a')
print >> backuplog, (restformat.subtitle('END BACKUP'))
print >> backuplog, ('\n\n')
backuplog.close()

restformat.py

#!/usr/bin/env python

def title(mytitle='reStructeredText Title'):
'Returns mytitle formatted as a reStructeredText title.'
return '=================================' + '\n' + mytitle + '\n' + '================================='

def subtitle(mysubtitle='reStructeredText Subtitle'):
'Returns mysubtitle formatted as a reStructeredText subtitle.'
return mysubtitle + '\n' + '---------------------------------'

Remember, one of my requirements was to have an easy to read log of what was going on, that is why I used reStructuredText formatting. Below is a sample log output from the Python script.

=================================
Mon May 11 21:46:27 2009

Basic Bible Stats

2009-04-22T12:19:00.003-04:00

Here are some basic Bible statistics based on the original languages.

Old Testament - From Van Pelt, Miles V. and Gary D. Pratico, The Vocabulary Guide to Biblical Hebrew, (Grand Rapids, MI: Zondervan, 2003), ix.

Total number of words: 419,687
Total vocabulary: 8679

New Testament - From Statistik des neutestamentlichen Wortschatzes (Zurich, 1958) in Metzger, Bruce M. Lexical Aids for Students of New Testament Greek, (Grand Rapids, MI: Baker, 1997), 1.

Total number of words: 137,490
Total vocabulary: 5436

This means that the Hebrew Bible contains 3.052 times the number of words as the Greek New Testament. Further, the OT has 1.596 times the number of vocabulary terms as the NT.
