BackupPC_archiveHost_s3
|
||||
=======================
|
||||
|
||||
This is a Python script that acts as an interface between
|
||||
[BackupPC](http://backuppc.sourceforge.net/) and
|
||||
[Amazon S3](http://aws.amazon.com/s3/). It uses BackupPC's
|
||||
[archive function](http://backuppc.sourceforge.net/faq/BackupPC.html#archive_functions)
|
||||
to extract a tarball and split it into chunks, like the normal archive
|
||||
function. Then, the chunks are encrypted using gpg and transmitted to
|
||||
S3 using [Boto](http://code.google.com/p/boto/).
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
I wrote this script some years ago, and can't remember how to get it going.
|
||||
But, here's going to be my best guess :-)
|
||||
|
||||
1. Install prerequisites
|
||||
|
||||
You will need Python, [Boto](http://code.google.com/p/boto/), and a
|
||||
working BackupPC installation.
|
||||
|
||||
2. Download and install this script
|
||||
|
||||
Something like this seems like a good idea:
|
||||
|
||||
cd /usr/local/src/
|
||||
git clone git://github.com/rtucker/backuppc-archive-s3.git
|
||||
|
||||
Then create a link from `/usr/share/backuppc/bin/` to here:
|
||||
|
||||
ln -s /usr/local/src/backuppc-archive-s3/BackupPC_archiveHost_s3 /usr/share/backuppc/bin/
|
||||
|
||||
3. Configure this script
|
||||
|
||||
Create a file in this directory called `secrets.py`, based upon the
|
||||
`secrets.py.orig` file. It should have your AWS Access and Shared keys,
|
||||
a passphrase that will be used to encrypt the tarballs, and, optionally,
|
||||
a path to a file that contains a maximum upload rate in kilobits per
|
||||
second:
|
||||
|
||||
accesskey = 'ASDIASDVINASDVASsvblahblah'
|
||||
sharedkey = '889rv98rv8fmasmvasdvsdvasdv'
|
||||
gpgsymmetrickey = 'hunter2'
|
||||
speedfile = '/var/cache/speedlimit.txt'
|
||||
|
||||
If you use the `speedfile` option, you can change this on the fly to
|
||||
limit upstream bandwidth usage during peak hours, etc.
|
||||
|
||||
4. Configure BackupPC
|
||||
|
||||
From the BackupPC configuration interface, go to `Edit Hosts` and add a
|
||||
new host, `archiveS3`, which looks like the existing `archive` host.
|
||||
Save this, select the `archives3` host, and then `Edit Config` for that
|
||||
host.
|
||||
|
||||
Change the settings on each tab as follows:
|
||||
|
||||
Xfer:
|
||||
XferMethod: archive
|
||||
ArchiveDest: /var/lib/backuppc/archives3
|
||||
ArchiveComp: bzip2
|
||||
ArchiveSplit: 500
|
||||
ArchiveClientCmd: $Installdir/bin/BackupPC_archiveHost_s3 $tarCreatePath $splitpath $parpath $host $backupnumber $compression $compext $splitsize $archiveloc $parfile *
|
||||
|
||||
Backup Settings:
|
||||
ClientTimeout: 720000
|
||||
|
||||
That should be just about it. Note that `ArchiveDest` is where it will
|
||||
stage the tarballs before it uploads them; this must have enough disk
|
||||
space for your archive! `ArchiveSplit` is the size of each tar file,
|
||||
in megabytes; you may want to adjust this for your needs. Also, the
|
||||
`ArchiveClientCmd` is the default, except with the `_s3` added.
|
||||
|
||||
5. Use it
|
||||
|
||||
Go to the main page for the `archives3` host and click `Start Archive`.
|
||||
To start with, just tick the box next to the smallest backup you have,
|
||||
then `Archive selected hosts`. Go with the defaults (which look
|
||||
suspiciously like what you set on the Xfer tab, do they not? :-) and
|
||||
then `Start the Archive`.
|
||||
|
||||
Watch syslog and hopefully everything will work.
|
||||
|
||||
backup-manager.py
|
||||
-----------------
|
||||
|
||||
There is a companion script, `backup-manager.py`, that can be used to see
|
||||
what's on S3. Run it with no arguments to get a listing of backups and
|
||||
their ages, or use the `--help` argument to see what it can do.
|
||||
|
||||
The "crown jewel" of this whole system is the `script` command, which
|
||||
produces a script that can be used to restore a backup. It uses S3's
|
||||
[Query String Request Authentication](http://docs.amazonwebservices.com/AmazonS3/latest/dev/index.html?RESTAuthentication.html#RESTAuthenticationQueryStringAuth)
|
||||
mechanism to generate temporary URLs to download each file required to
|
||||
restore a backup.
|
||||
|
||||
Each night, from `cron`, I run a script:
|
||||
|
||||
#!/bin/sh
|
||||
BACKUPMGR=/path/to/backup-manager.py
|
||||
|
||||
# Delete all backups older than 30 days.
|
||||
$BACKUPMGR delete --age=30
|
||||
|
||||
# Create restore scripts, valid for one week, for all of my computers
|
||||
cd /home/rtucker/Dropbox/RestoreScripts/
|
||||
$BACKUPMGR --expire=604800 --host=gandalf script > restore_gandalf.sh
|
||||
$BACKUPMGR --expire=604800 --host=witte script > restore_witte.sh
|
||||
# etc, etc
|
||||
|
||||
# Output a list of what's on the server
|
||||
$BACKUPMGR
|
||||
|
||||
The output of this is mailed to me, so I always know what's going on!
|
||||
|
||||
FAQs
|
||||
----
|
||||
* BackupPC is written in Perl. Why is this thing written in Python?
|
||||
|
||||
I know Python much better than I know Perl, so I wrote it in Python.
|
||||
The good news is that BackupPC doesn't care, but it does mean this
|
||||
probably won't be part of the BackupPC main distribution any time soon.
|
||||
|
||||
* Is this project dead?
|
||||
|
||||
You could say that. A lot of [my projects](https://github.com/rtucker/)
|
||||
are one-off scripts that solve a very specific need I have, and I don't
|
||||
put too much thought into making them useful for other people. This
|
||||
script works for me and (sorta) meets my needs, so that's where it is.
