Fw: Trying a recover; showing no files from a level 3 backup last night

Posted by Michael Leone 
I've had a long standing job that backed up a file server as level 1; been
running this job for years. But, due to networking issues outside of
Networker, I had to change the level to level 3, because level 1 wasn't
finishing in the allotted time anymore. Changing it to level 3 allowed the
job to finish.

(this is on Windows, BTW)
So today, I went to do a recover from that file server, and I don't see
any files backed up from the directory I want last night. In fact, I
don't see that directory at all (I do see other directories).

Yet if I look at the log from the level 3 backup job last night, I do see
the directory I want being backed up, and a total of 1.5G being backed up
(as level 3).

86704:save: Successfully established DDCL session for save-set ID
'3330977583' (nt_san1:G:\departments).
nt_san1: G:\departments level=3, 1569 MB 00:32:07 1788
files
Completed savetime=1569369903
94694:save: The backup of save set 'G:\departments' succeeded.
94694:save: The backup of save set 'G:\departments' succeeded.

Yet doing a standard Windows recover, I don't see that folder as having
anything backed up from it last night.

Why not?

And how can I get to see it, so I can choose just the one file I want?

This is NW 8.2.4 (yes, I know, out of date; I have to migrate it to a new
19.x server sometime real soon now. Once we finish this datacenter move
....)

Any help appreciated. I'm sure it's just something I am misunderstanding,
but I don't know where ...

This is not an ideal solution but try it out. On the client open command
prompt as administrator, go to the folder in question. Now run the recover
command here. See if this works.

This is Windows; I am using the GUI program winworkr.exe, not the CLI
recover command. I need the GUI; it's a lot easier to choose 1 file,
especially if you are unsure of what the name was. :-)

Plus, some of the other guys in my department seem to think that CLI is
outdated and unnecessary, no matter how times I show them that it is not.

Hence, I need a GUI solution, preferably a native Windows app. I still
don't understand why winworkr.exe doesn't show them to me, when clearly I
see in the log that they are being backed up, as level 3.

and no, running winworkr.exe from the desired directory doesn't fix it.

Try doing the recover not through any client tool but through the
NetWorker admin GUI that you launch via NMC.

We've had bizarre issues similar to what you're describing on one
particular Linux host, and when my colleague opened a ticket with EMC
about it, their response was basically "use NMC".

You can do a recover from directly inside NMC? Learn something new every
day ...

Same problem. On the Sep 24 backup, I do not see the "G:\Departments"
backup that the log (and mminfo) tell me it did ...

If I click "Versions" I see an entry from the time that the backup I want
happened (8:05PM), but I don't see any way to choose that as the set to
search. Highlighting it tells me I can't do that on Windows, since I am
also selecting the WINDOWS ROLES backup.

So I guess I need to look into this further. I see the version I want - at
8:05PM - but I don't know how to look at the list of files in that
version, to choose the file I want ...

Thanks, tho. I had no idea you could do a recover this way, even if I
don't yet know how to fully utilize it the way I apparently need ...

OK, good to know I'm not the only one. :-)

First - convince your colleagues that NW works from the command line. Period.
Everything you run via a GUI will first be translated into a command and then be executed. There is no 'parallel world'.
The bad thing about it is that you can/must determine whether a problem exists for NW (core) or the GUI.
The good thing is that - if the GUI fails - you can still try to use the CLI. And yes - this often works.
And do not foget that you can add other options like more verbosity and debug levels from the CLI.

There are a bunch of 'hidden' limitations with winworkr which are not mentioned at all. The major ones are:
- no feedback for indirect restores. For example if you recover from a cloud (ECS) save set the GUI will just not
change for hours ... until the save set has completely finished the recall to the DD active tier. Then it just takes
seconds/minutes to run the actual recover process.
- limitations if you open a huge directory for browsing. Usually, you can even see the files names rushing through at
the bottom of the window but then it is time for internal hashing ... and this can take hours depending on your system
capabilities. DO NOT TOUCH THE GUI DURING THIS TIME! - It will return and you can continue but it will just take
time until its content will appear. Unfortunately, the GUI is just showing nothing or 'framed' icons while you might
think that the system hangs.
Such usually occurs if you have hundred thousands/millions of files in the directory (yes, some apps to that :-( )
In your directory with 1788 entries, this should not happen ... but who knows.
- The new (NW recover) process clearly overcomes this issue ... until you have less then 200.000 entries in the
directory. At least you receive an error message like (too many entries) but you never know what the limit is. It is,
however, stated in the Admin Guide when you browse the save set tree to define the save set list for that client.


To help you may I suggest that you recover the save set to a temp directory and get the files you want from there.
Sorry, but I do not have a better solution.

All times are synchronized t our Domain Controllers, and are correct.

The user reported that they worked around the issue, so I didn't need to
do the recover. Regardless, I set the daily backup to level 1, as it
always had been, so I hope that resolves the issue.
