Our project PowerBackupSystem (#95), developed into many stages,
which I would like to describe here.


I)EFIKA as Desktop computer
First of all we have used the Efika as a desktop computer to find out its performance and future possibilities.
As we would like to transfer, take over, transmit the Efika we have made our own case with passive power supply see fig. 2.


Figure 1: First configuration Efika desktop computer


Figure 2: Efika Desktop computer in our case with passive power supply

The desktop computer has been developed in operational system Linux in distribution Debian with graphic shell Fluxbox.
On the computer we have intalled web browser Iceweasel, word procesor Abiword and video player. See fig. 3.

II)EFIKA as backup system
Lets go back into our project. Backup system is connection specific hardware with tune software.

1.Hardware backup system made of these components

Main board EFIKA
Passive power supply
Compact Flash/IDE reduction
FAST SATA II controller
Compact Flash cart
2 x HDD SATA
Temperature sensor for measurement core temperature (fig. 4.)
Present form of backup system is not convenient (see fig 5.), but we work on Case with compact proportion.

2.Description of connection hardware components

Core of backup system is mainboard Efika. Via 2.5“ conector is connected reduction compact Flash-IDE, where is Compact Flash Card.
In PCI slot is insert FAST SATA II controller. To FAST SATA II controller is connected two SATA HDD.
To serial port is connected temperature sensor for measurement temperature backup system. Efika with SATA disc is supply passive power.

3.Software for backup system

Operation system is approved, well worked Debian which has been tried in desktop. Debian is instaled without graphic shell.
There is also instaled SW RAID controller setting up as a mirroring, FTP server, SAMBA, Smart deamon, PHP server a HTTP server.
All of these structures OS, are adjusted by means of web configured pages and specific scripts.

Operation system along with control software (web pages and scripts) recorded on Compact Flash Cart.
This Flash Cart set only for read data. This solution selected, because was safe and easy to upgrade.
When user will get new operation system or control software, that easy change Compact Flash Cart.
The Compact Flask Card have another advantages such as low power consumption and haven't wheel component, than classic hard disk.

4.Description od facilities

After switch on back up system will be boot operating system and our control software.
User conecting to back up system via ethernet cable.
User can connect from any operating system but there must be graphic web browser.
After log on to graphic pages the browser will set up names, passwords and level of permission particular users.
See fig. 8. and 9. On those configuration pages there is possible to find any other informations about in which stage the back up system are appearing.
There is displayed a temperature of discs (see fig. 7.),
a temperature of core back up system, status of data free on the discs and also a list of all user’s accounts.
User’s can store their dates which they would like to safely store on back up system by using SAMBA record or by using FTP client.
User’s can store their dates which they would like to safely store on back up system by using SAMBA protocol or by using FTP protocol.
Dates are safely stored on two SATA discs. If there are any disc with faults the SMART demon sends an email to a user.
If the system is being overheated the temperature sensor switch on a main ventilator.
If there is inadequately fall of temperature the system switches off by its self.

9.Construction backup system case

It was necessary to design the case to safe features of resource system and make sure this system will realize quality of these facilities.
By this time we have designed just a model (see fig. 10.) and graphic project (see fig. 11).

III) Conclusion
Ours goals has been realized. The project is in final stage. We left out only partiotions encrypted,
because there has been a big demand on service and the whole system would slow down.

IV) To do and improvement

translate configure web pages to English language
improvement web pages graphic design
make final case version for back up system
try another communication protocols such as SFTP a NFS
HDD connect via Hot Swap




We hope you will be happy with our project and we looking forward to cooperationg with you again soon.
