Incremental backup behavior

If you really want to see, what has been backed up, may I suggest that you run the nsrinfo command as follows: nsrinfo -vv -t nsavetime clientname | more

Here is the output of 2 subsequent inc job.. looks like it is backing up the same data ...

So what? - we cannot say whether this is right or wrong. We can just investigate the result. For example these could be hidden files.

I just wanted to show you a way how to investigate what has been backed up. And do not forget that an empty save set will at least create some bytes (to maintain the absolute pathname). On the other hand, IMHO this is o.k. as there will be an (empty) entry in the save set list which shows you that NW really executed the backup.

Yes, just like you mentionned, the save sets should show very little size, almost empty.

But even after a full backup the incr is always the same size as the full. If I add a file is just increment...

Deleted the client and recreated it... Now the incr are working as supposed to!
I'll see if this still will work in few hours!

You can even see the exact size of a save set if you specify the length of the sumsize attribute - for example: mminfo .... -r "....,sumsize(10),....)

If you now add all "NSR size ..." values which are reported in the lines starting with "WIN ASDF"you should achieve almost the same size as reported by the sumsize attribute.

So if you want, you can really investigate what exactly has been backed up and with which size.

Thanks for the hint really appréciated!

Well after calculating the numbers, backup where actually full not incremental despite the fact that incr was specified. Looks like the last full could not be retrived, been testing with another client and having the same issue.

Tried new client, new group, new policy, specifying -c [ client_nam] but same behavior no luck.

Well - I don't know yet.

If there is no full backup (yet), then NW will tell you and will actually run a full.

Let's say that you only backup one single file with 10MB in size which will always change in the interim - one bit/byte is enough. Consequently, the first backup will show as a full, and each later backup as incremental. If the change is minor you will always see that you have the same save set size but the contents is not the same.

So you should look very precisely at your files and their access times (as reported by nsrinfo).

BTW - which NW version do you use at all?

We are on version
