I am looking to use BackupPC in an environment with several roaming
laptops and a wad of disk on a hosting site. I am not a sysadmin expert
and looking at the doc it is not readily apparent if this is something
reasonable to attempt. There are some mentions of installing things as
root (not possible), adding Perl libs (perhaps they can be added in my own
account?), etc. And then there is the whole DHCP and client discovery
thing. This post is to test the water and see if I am even close to the
right solution with BackupPC. It would be great if someone could point me
in the right direction.
- Hosted system on which I can run Perl but need to install some of the
required modules (e.g., rsync) in locations other than the
default/standard one since they are not installed by default. BackupPC
would be installed there.
- Have client periodically wake up and talk to the server over HTTPS or
SSH to initiate a backup (I don't mind having something on the client).
The backup could then proceed as client push or server pull, tunnels,
whatever is best.
- Only the files that are changed would be uploaded (assuming incremental)
- The files are pooled on the server but more over, changes between
versions of the files are stored as diffs (think RCS, bdiff, ...)
- even better the files on the server are stored encrypted and compressed
One concern I have is whether this whole process just too heavy for a
standard/typical web hosting server (i.e., are the sysadmins there going
to flame me for trying something like this)? I am not buying compute
time, just web/file hosting. If I start sucking gobs of CPU it would not
go unnoticed.
On a slightly different note, someone mentioned that BackupPC would copy
things to the server over time where possible so as you roam around it
would get a bit here and a bit there. A bit like a rolling backup. Where
they smokin' something? did I misunderstand? really really?!
Thanks for your help and advice
Jeff
