About three years ago I wrote a post on how to setup duplicity and by that time I was using the program for about two years. Not long after I made that post I realized that it wasn't the best backup solution for me. The two biggest reasons why I ditched duplicity was first, it was slow and second it ate up a lot of disk space. The two reasons go hand-in-hand. Duplicity doesn't do any deduplication, which means if I move a directory that is 100GB, and there was only 1GB of changes to existing files, the entire backup for the day would be 101GB.

Sometimes, for whatever reason, you may want to remove the encryption from a device. Perhaps you didn't think a device needed to be encrypted initially.
When setting up a RAID array I have always opted for either RAID 5 for arrays with less than five drives or RAID 6 when there are more than five. It wasn't until recently that I noticed how much of a penalty there is for running a RAID 6, six IOPs while the penalty for RAID 5 is four IOPs. When a drive has failed in one of my RAID 6 arrays, I never saw the rebuild speed get above 75MiB/s even though the failed drive was capable of 150MiB/s. For smaller arrays, that may not be such a big deal. When it's a 16TiB array it will take about two and a half days to rebuild.
Recently, I've been having some issues with dd-wrt on my Linksys wrt-1200ac router. I'm not certain if there is a bug with the firmware or if there is something wrong with the router itself. After flashing the router, it would work great anywhere between a day to a week before not being able to access the internet or becomes unresponsive. The only way that I was able to fix it was by doing a factory restore, which means I had to reconfigure my router.
In cloning my PS3 and PS4 hard drives using the
ddcommand, and using the
status=progressI was only able to see how much has been transferred, how long the command has been running, and the speed. The only thing that was missing was a estimate of how long it would take to complete. Additionally, a progress bar would have been nice. While waiting for the process to complete I looked for a tool that would provide what I was missing.
Back in 2008, I purchased a Sony PS3 along with my 40" Samsung TV. I was lucky to get a model that is able to play PSX and PS2 games so I definitely want to hold on to this for as long as I can. Unfortunately, the 80GB hard drive has become rather limited and would like to free myself of that constraint. Over the years I have accumulated various computer parts and one of them was a 256GB OCZ Agility 4 SSD, so I decided to put it to use.
Create a Backup DriveThe first and obvious thing to do is BACKUP YOUR DATA.
What is Duplicity?Duplicity is a command line tool used for incremental backups to local or remote storage, which supports Amazon S3, Rackspace Cloud, Dropbox, Google Docs, rsync, ssh, FTP, FTPS, and webdav.

Generating GPG KeysAlthough duplicity uses GPG by default, this can be skipped by adding the --no-encryption option to the command.
# gpg —gen-key or # gpg --full-generate-key
