I have backuppc running on a very very small system.
It is a NSLU2 linksys running openslug. The NSLU2 is a arm based system
with 1 ethernet 100mbit and 2 usb 2.0 port used to connect to disks.
There is only 32 meg of ram in the box. The box runs a 2.6 linux kernel
and had perl and apache already ported. Making backuppc run on the box
was easy. It just slow backup of about .6 mbytes.
The system is has very little processing power or memory. I am using
tar to move file between unix hosts and the backup system. Passing
everything thought ssh is causing a lot of overhead. I would like to
create a new transport that using tar and open a port to stream the
tar file to the backup system. This would remove the overhead of ssh
from the transfer.
I would also like to be able to compress file but the backup host is
too slow to make this happen. I would like the host being backup to
compress the file before sending them (read the output of the tar stream
and then compress the data.
I would also like to be able to compute the MD5 on the host being backedup.
The above changes should be able to be made by creating a new xfer type
that handle this way to create the pc/host directory with the extract
same layout as already exists but is much lighter on the backup host.
I would like to check to see if anyone has started down this path before
modify the code. I would also like to be able to send in the patches to
have this code included in backuppc.
I see this a multi step process getting each step running and then
submit the work back to project. I am willing to do the work.
