Ceph Training opensourced

 

Besides several other trainings, such as gitlab, foreman or graphite/grafana we’re happy to announce our newest member in the NETWAYS OpenSource training community.

You might have guessed it after reading the headline, we’ve published a ceph training.

 

This training is designed as a two days hands-on training introducing Ceph, its basics, cluster setup and many best practices.

The training participants will get an in-depth insight into the Ceph basics and configuration. They also learn about Ceph Cache Tier, Rados Gateway, RBD, CephFS, Monitoring and Sizing.

– README.md

As ceph is a project with huge momentum, not only regarding spreading but also development, changes are certain to happen.

The training right now is not very specific regarding OpenStack-Integration, so this will be in the focus in the next iteration.

Commits to the trainings are always welcome!

When you’re interested in a training with more interactivity and personal discussion, feel free to get an overview here.

A personal Linux backup solution

Having personal backups is a must, but what can you do if you don’t have a mac that runs timemachine?

My first instinct was using the tool of choice of a friend: duplicity. It’s free software, does encryption and incremental backups, what more could you want? But duplicity does not offer a very user experience. The docs are work in progress, the –help is a bit of a mess and the man page is too verbose for a quick start. Obviously I have little problem reading and learning before using a tool, which is why I gave up and looked for a different one.

Restic does all what I want and duplicity can, but it has a good documentation, bash completion and other optional bonuses for making usage and, in turn, my life much easier.  It makes sense to think about what to backup before thinking about the right tool. I only want to backup from ~, I don’t care about `/etc` or other places with config or data, it would be no use to me when someone was to throw this laptop down a bridge. So just how much is lying around in my home directory?

$ du -h -d1 /home/jflach | grep "G" 
1.9G	/home/jflach/i2
4.3G	/home/jflach/.ccache
20G	/home/jflach/git
108G	/home/jflach/vmware
6.6G	/home/jflach/.cache
20G	/home/jflach/Documents
1.2G	/home/jflach/.thunderbird
3.3G	/home/jflach/Downloads
5.6G	/home/jflach/.vagrant.d
171G	/home/jflach

Luckily I have no folder with an upper case “G” in the name and I can see that over 50% are used up by vmare/. I don’t really need to backup my virtual machines, it’d be annoying to lose them but no reason to panic. `.ccache/`, `.cache/` and `Downloads` are completely irrelevant, bringing the total down to just above 50GB.

Back to restic. Creating a new local backup repository is easy:

$ restic init --repo /tmp/backup                                                                                                    
enter password for new backend: 
enter password again: 
created restic backend 929fc4f740 at /tmp/backup

Please note that knowledge of your password is required to access
the repository. Losing your password means that your data is
irrecoverably lost.

Now the for the actual backup, I have a file containing the excluded directories:

$ cat ~/.config/restic.exclude
Downloads
vmware
.ccache
.cache

And the command is simply:

$ restic -r /tmp/backup backup ~ --exclude-file=.config/restic.exclude
enter password for repository: 
password is correct
scan [/home/jflach]
scanned 10123 directories, 64039 files in 0:00
[11:07] 100.00%  76.166 MiB/s  49.612 GiB / 49.612 GiB  74162 / 74162 items  0 errors  ETA 0:00 
duration: 11:07, 76.12MiB/s
snapshot dd45c515 saved

It took eleven minutes on my machine to encrypt and compress about 50GiB of data. Restic starts a few threads and voraciously consumes CPU time and memory as it runs. Get yourself a fresh cup of coffee, working is no fun while the tool runs.

All that’s now left to do is to copy the directory to some external server or hard drive. Restic offers support for common sync tools like sftp, google cloud or rclone, whatever you use it will be your job to automate and define its behavior.
