Re: [BackupPC-users] Correct rsync parameters for doing incremental tran

Hi Les,

using a outdated image for restoring and "manually" copying things over is not an option for me. The Server is a domain-controller with several profiles, running two databases and have proprietary software installed that relies on registry settings and all that silly stuff.

I don't see another chance then using a nightly created image atm and I can live with space-waste, no pooling and heavy IO but I just want this in-file incremental rsync to work as expected because the only thing that breaks it is that I can't transfer 80 GB of data through a DSL50 line every night. This would exceed the time-window I have for the backup.

Thank you anyways,

Andreas

Hi Les,

excuse my floppy frase: Real time recovery is not what I'm looking for. I
ment I want to be able to get the system into a workable state simply by
downloading and restoring from an image. If I need to manually assemble the
system disk from a file based backup and fiddle around with a non-bootable
and hard to debug windows server that's not a solution for me. Repairing a
broken windows installation is an extremely time consuming pain compared to
react on some "file not found" or "wrong path" error messages from a
linux-os which directly leads to the problem.

I understand your concept with restoring a (not necessary up-to-date) image
and doing a file based restore on top, but I have never tried this and don't
feel so comfortable with this.

I don't put the images (clonezilla or VM files) into backuppc at all.
The copies just work as they usually do. And once they are running,
you just have the same process you would have if someone deleted
something accidentally to bring the files back from backuppc.

Please can you tell me more concrete about the windows-version you did this
with and did you use the "normal" ntfs file-system driver or ntfs-3g while
doing the file-based "overlay" restore?

I don't do an overlay restore. Just smb or rsync.

How often have you done this successfully or better have you ever had
problems with file permissions, lost attributes or anything else? Or have
you done additional steps for getting the system drive bootable again?

The (possibly outdated, but complete) VM image or clonezilla backup
will boot.   The windows systems I back up are either single-purpose
application servers where I know how to reinstall that app if needed,
or generic file servers where there isn't much windows magic.   There
are more complex windows servers in the company where it might be
important to track frequent registry changes and program updates, but
someone else manages them, probably with proprietary programs. If I
had to do those, I'd probably at least use the volume shadow copy
tools during the backup.
