Re: [rdiff-backup-users] problem while restoring

Hi Andrew,

Thanks for such a great response.

Here are the answers of your questions::

>>What version of rdiff-backup are you using?

I am using rdiff-backup1.1.15

>>Are you using Cygwin? Or are you using the new native Windows port?

yes I am using Cygwin.

>>What version of Python?

Python2.5

>>What filesystem are your drives using? Are they network-mounted?

I am using NTFS and FAT32.

In case of NTFS- The problem that I told you earliar.

In case of FAT32- It give me one extra warning only "Hard linking not supported by filesystem at <drive name where I want to restore like F:/destdir>" rest is the same as in the case of NTFS.

No they are not network mounted, I am using all the things on my local machine.

>>Can you do the restores without using the --force option?

Yes Andrew, I am able to do it without --force option but if the directory or file already exist, it gives error "restore target <directory name like F:/destdir > already exist, specify --force to overwrite " (No prob with this).

>>Can you restore using one of the other date arguments? For example, "rdiff-backup -r 1B" or "rdiff-backup -r 2B" or "rdiff-backup -r 3B" etc.

Yes, I tried to restore using 1B,2B... date argument but the result is same. Are there some other date arguements beside B and D? I know only these two.

** Now I am giving you the output when I run the command with higher verbosity.

Restoring from latest increments that is just one day older(no error and restore successfully):---.

--- I dont know why this error is comming. Please suggest me what should I do.

--- How can we restore the incremental backup that has taken one hour or two hour before. Like above $rdiff-backup -r 1D(or 1B) dest I:/dest1 restore the incremental of one day older suppose I need to restore just one hour older or two hour older.

Please provide me your great suggestions.

Thanks & regards

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::

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

Hi Madan,

This is an unusual error and indicates that rdiff-backup is having some trouble with the actual files it thinks it is restoring from. Since you mention that you are using it on Windows, it may take time to sort this out. First, here are some questions:

What version of rdiff-backup are you using?

Are you using Cygwin? Or are you using the new native Windows port?

What version of Python?

What filesystem are your drives using? Are they network-mounted?

Can you do the restores without using the --force option? That option can be dangerous and not do what you intend.

Can you restore using one of the other date arguments? For example, "rdiff-backup -r 1B" or "rdiff-backup -r 2B" or "rdiff-backup -r 3B" etc.

Finally, try running rdiff-backup with a higher level of verbosity, such as -v8 and sending the output to the mailing list. This will help show exactly which file rdiff-backup is working on when it encounters the failure. After you know which file is causing the failure, you can then go and find out more about that file. In this case, we know that Python is not reporting that it is of type 'FileType' -- that leads to the question, well, what type is it?

Andrew
