Adding memory space to a SoHo

Recommended Posts

Hi,

 

I recentlytried to make a backup of a SoHo system using SSH (through putty,

an SSH, Telnet and Rlogin client for windows). I was able to get as far as creating

the file. However, I could not go any further because the new file had used up all

the available free memory that was there in the system.

I understand that this device has little space by nature and that if there is

need or want for call recording or more than a little voice mail, one should

look for a different setup. I, for instance, configure the SoHo systems that I deliver

with short time parameters for call recording, cdr storage and such and I do

not tell the end users that there is call recording capability at all. However,

there are some very basic and crucial maintenance duties that should be

performed, like backing up the system and being able to restore it and those

require memory.So, please,could we get a step by step procedure to perform these needed duties

on a SoHo? By step by step I mean an algorithm or a guide “for the rest of us” (field

people that are not IT guys and much less know anything about Debian Linux).

 

I know thatwhat I am asking for is going to take effort, but I assure you

that it will save many headaches and will allow us to put more snom products in the field.

 

In short,the 3 very basic algorithms (or step by step procedures if you like) that I askfor are:

 

1. Enabling a USB memory stick to makespace available for the SoHo system to use.

 

2. Making a system backup that woulduse precisely the memory created in the previous procedure.

 

3. Making a system restore from thebackup stored if, Heavens forbid, a disaster strikes.

 

I will be much obliged and pledge that if thispetition is granted I will promote snom products in my market.

 

Thanks in advance.

The snom ONE mini is running a standard Debian distribution for ARM. This is good news, because there is plenty of information and manuals available e.g. from debian.org.

 

USB memory sticks are automatically detected by the system. After you login, you should see /media/usb; there you can make your backup.

If you want to restore the backup you have to use the command tar xvfz /media/usb0/backup130109.tgz (working directory /usr/local). This is not only interesting for disaster recovery, this is also interesting if you want to try things out with a safe way back.
