h1. Backup Scheme

h2. Borg Backup

I discovered "BorgBackup":https://www.borgbackup.org/ a while back and decided to give it a chance.  So far it works very well.

h3. Install

<pre>

$ sudo add-apt-repository ppa:costamagnagianfranco/borgbackup

$ sudo apt install borgbackup

</pre>

h3. Create Repo

# This assumes that the backup repo is located on file2. In the cases shown below file2 is mounted via nfs.

# Create backup repo and make a note of the password.

<pre>

$ borg init --encryption=repokey /mnt/file2/backups/Documents

</pre>

h3. Create Backup

# Be sure file2 is mounted via nfs.

# Create backup; note that the date/timestamp is a convention but the backup can be given any name.

<pre>

$ borg create --stats --progress --compression=lz4 /mnt/file2/backups/Documents::20220402_1202 /mnt/phalanx/Documents    // can give any name

$ borg create --stats --progress --compression=lz4 /mnt/file2/backups/Documents::{user}-{now} /mnt/phalanx/Documents     // use built-in variables

$ borg list /mnt/file2/backups/Documents/

</pre>

h1. Legacy Backup Scheme

Note these instructions are obsolete but are left for reference.

h2. Overview

The following items are currently backed up:

* Documents folder

* Pictures folder (includes iPhoto library)

* Trac site including git repo

Backup tarballs are compressed with "lrzip":http://ck.kolivas.org/apps/lrzip/.  Backups are stored on phalanx, on -saga-, and on an external HDD. I really should do this at the very least every 6 months, but right now I do it only when I remember.  I should probably create a recurring calendar reminder and do it quarterly...

Images (JPEGs) are using a neato compression software I found called "packJPG":https://github.com/packjpg/packJPG and my own wrapper utility called [[PhotoCompressArchiver|Photo Compress Archiver]].

h2. Steps

# Make sure the latest lrzip is installed and phalanx is mounted.

# On prometheus, change to the HDD:

<pre>

$ cd /Volumes/Macintosh\ HD/

</pre>

 Make a backup directory corresponding to the current date, name it according to YYYYMMDD (e.g. 20131117 for November 17, 2013) format:

<pre>

$ mkdir 20131117

$ cd 20131117

</pre>

# Create tarball for Documents folder:

<pre>

$ tar cf documents.tar /Volumes/storage/Documents

</pre>

 Compress Documents tarball:

<pre>

$ lrzip -L 9 documents.tar

</pre>

# Copy pictures folder to temporary location:

<pre>

$ cp -R /Volumes/storage/Pictures ~/Desktop/temp/

</pre>

 Run PCA on copy:

<pre>

$ ./pca -f ^\\._.+$ ~/Desktop/temp/Pictures 2>&1 | tee pca_log_20170302_1639.txt

</pre>

 Create tarball of compressed pictures

<pre>

$ tar cf pictures.tar ~/Desktop/temp/Pictures

</pre>

 Compress Pictures tarball:

<pre>

$ lrzip -L 9 pictures.tar

</pre>

# To create Trac tarball, you must ssh into phalanx (create a separate tab), create the tarball, then copy it to the `storage` share:

<pre>

<from phalanx>

$ sudo tar cf trac.tar trac

$ sudo chown dsorber:dsorber

$ mv trac.tar /storage

</pre>

 From prometheus, grab tarball and compress:

<pre>

$ mv /Volumes/storage/trac.tar .

$ lrzip -L 9 trac.tar

</pre>

# Remove intermediate tar files:

<pre>

$ rm *.tar

</pre>

# Copy backup folder to phalanx and the external HDD.

# Finally, rsync backup to saga:

<pre>

$ rsync --bwlimit=1024 -Pvhe ssh * dsorber@saga.homelinux.org:/storage/backups/20170301

</pre>
