NethServer Version: 7.3.1611
I have noticed the following posts:
I still have some questions. I guess my question is regarding to Duplicity. I decided to create this new topic.
The first question is regarding to the use of multiple USB disks. Does it work out of the box?
I have noticed that the next backup fails when I remove the back-up files from the USB disk (/mnt/backup). I have worked around this by removing the folder in [ /var/lib/nethserver/backup/duplicity/ ]. The backup works again, by executing the [ /sbin/e-smith/backup-data ] command.
I am currently re-running the first back-up to reproduce the above. I just want to verify if the behaviour is consequent (I am using this product for the first time).
What I would like to know is if there is anyone who is using the backup as is (out of the box) with multiple USB hard disks. Is the above behaviour normal? Or am I dealing with a coincidence? Please bear with me - as the backup process takes several hours (I can test it myself but it takes long - some help of an experienced user would be very much appreciated).
The second question is with regards to compression ratio. I have noticed that the files produced by Duplicity are tar.gz volumes. What is the best way to increase the compression ratio? I guess I could pass the environment variable “GZIP=-9” system wide - but what is best practice? How am I supposed to accomplish this on a system running Nethserver?
By the way: is there a reason to use volumes of 250M? Is it possible to increase these to eg 1000M?
I am hoping to use the backup module as is with multiple USB hard disks. I am willing to add a hard disk and use rsync if required… but I prefer an out of the box experience.
