[rdiff-backup-users] problem while restoring

[Madan Kumar]

Hi All,

I am using rdiff-backup on windows XP and on Vista.

I am abe to take the backups successfully.

While restoring backups I am running following command:

address@hidden ~

$ rdiff-backup --force -r now adest/ I:/adest1        

 

{adest/ keeps backup+incrementals; adest1/ is the Directory where to restore the backups }

 

I am easily restoring the data from current mirror ie by using above command. It restore current data(no problem).

I am able to restore the data with latest incremental(that I have taken one day back) by using following command::

address@hidden ~

$ rdiff-backup --force -r 1D adest/ I:/adest1 

 

But when I try to restore the data with second last (or any older incremental) that I have taken two days back by using following command::

 address@hidden ~

$ rdiff-backup --force -r 2D adest/ I:/adest1

It gives me error that I am not able to understand.

the error message is-:

Exception 'basis_file must be a (true) file' raised of class '<type 'exceptions.

I will try to make it more clear by giving one example-:

1-Suppose I have one directory in I:\ drive ie I:\Source\a1.txt

2-I am taking the backup of it by using $rdiff-backup -b I:/Source Dest/ (on 17/07/08)

3-Now on 18/07/08 I make changes to this directory and again taking backup: It will create one increment of name(a1.txt.2008-07-17T12;05803;05826+05;05830.diff.gz)

4- Again on 19/07/08 I change this dir and take backup. It will create one increment of name(a1.txt.2008-07-18T12;05804;05839+05;05830.diff.gz) 

5- Suppose today is 20/07/08

Now I am going to restore the backups:

*It is restoring the data by using current mirror that is latest. with command:- $rdiff-backup --force -r 1D Dest I:/Source1

 

*If I need the data that was on 18/07/08 I am able to get that with the command:- $rdiff-backup --force -r 2D Dest I:/Source2

It is restoring it by using (a1.txt.2008-07-18T12;05804;05839+05;05830.diff.gz) increment.

 

*If I need the data that was on 17/07/08 by using command:- $rdiff-backup --force -r 3D Dest I:/Source3

This time it should restore the backups by using (a1.txt.2008-07-17T12;05803;05826+05;05830.diff.gz) increment. 

But it is giving me the ERROR message that is written before.

 

 

 

Please help me out so that I can restore with any  incrementals whether it is latest or old.

 

 

       

 

 

 

Thanks & Regards
