                You're only using a .0.0 version?  Upgrade it.
Use the cli if the gui gives you problems.  There is help on how to do it under "dsmc help".

                I
tried a lot, but still can't find any "lost" file! does it have any
connection with my GUI client, because it has something wrong
look at this:

                with this magic command "dsmc restore f:\INT\3.2D\OC1\3P82024721H.jpg -pick -inactive"
I got one of my "lost" file, thank you again!
now, how can I get the whole folder F:\INT, I use GUI, but the "Point in time" confuse me, and I can't find my lost files!!

                thank you very much,
I use GUI, and I don't know how to set the "Point in time" option
I tried a lot, but can't find anything!

                start
the tsm client gui and in the view section choose display
active/inactive files, and than go to your folder and check your
files...

                Are you using gui or cli?  There is a manual for both of them you could read it.
Briefly, if you want to restore it with cli run
dsmc restore f:\INT\3.2D\OC1\3P82024721H.jpg -pick -inactive
Or you can use wildcards and use the pitdate/pittime parameters (check
the documentation for syntax). If you set the pitdate&time to just
after the files were backed up this will restore them.

                with your new command, I can find something like this,
25,899  B  03/02/2008 09:38:57    DEFAULT     I  \\kabmnt1\f$\INT\3.2D\OC1\3P82024721H.jpg
my question is how can I restore this file "3P82024721H.jpg" (sorry, I am a green hand on TSM, I mean what time should I set to restore this file)
and this file come out in dsmsched.log, look at this:
03/02/2008 09:38:46 Normal File-->            25,899 \\kabmnt1\f$\INT\3.2D\OC1\3P82024721H.jpg [Sent]
and also

I think now we will find the truth, thanks!

I use  "dsmc q backup f:\INT\ -subdir=yes" but I can just find files after the 2nd Mar. 11:00PM

for folders the mgmt class is standard
for files the mgmt class is default
any problem? about this policy domain config:

PROD_WIN_DOMAIN      ACTIVE             STANDARD         Yes                                   
PROD_WIN_DOMAIN      STANDARD         STANDARD         Yes   
I am sure nobody can recreate all the files and folders under F:\INT

                No
it would apply on a per file basis not for the entire directory tree.
So any individual files that were recreated were probably lost 6 hours
later. Are you really sure this happened though? Use the sql query
above, or "dsmc q backup f:\INT\ -subdir=yes" to check.

                if there are three folders in F:\INT, and each has their own files and folders
F:\INT\tom
F:\INT\tom\*
F:\INT\jimmy
F:\INT\jimmy\*
F:\INT\kevin
F:\INT\kevin\*\*
now someone delete the "INT" folder, and we keep only one verion for 10 days
and after some time someone recreate the folder "INT" then after servel hours
our last version been deleted because we just keep 3 version exist
the problem is this "someone" just create the folder "INT" and then our last version of
backup expired? so we lost our data...

                The
"expired" statement in dsmsched.log just means the client is telling
the TSM server to make them "inactive", its a bit of a confusing
message. Once inactive they are processed against the retention policy
you have setup, which is 1 version of deleted files which means you
should still have the very last copy of that file.
If somebody recreated the file and then it was backed up again 3 times
- that old copy might then be lost due to your verexists limit.
If you want to double check if the files still exist run this from the admin command line:
select * from backups where node_name='YOURNODENAMEINALLCAPS' and filespace_name='\\kabmnt1\d$' and hl_name='\INT\'
(be careful with your capitalisation (keep it as above) and the \'s)

                no one knows  what cause the files lost
we suspect the files under F:\INT deleted by somebody, but we can't find any proof
the files were recreate on 3rd,
I think maybe TSM delete all the files, can it possible?
look at this, dsmsched.log

                Were
the files "lost" on the 2nd by them being completely deleted from the
client? Were the files recreated between then and the 3rd before you
tried to restore them?

                thank you very much, I understand now
it is true that we change the files under F:\INT regularly
but there is still a problem
2008.3.3 user tell me the files under F:\INT are all lost
they find out this on 2008.3.2  2:00PM
I tried to restore the lost files from TSM on 2008.3.3
but I couldn't
my problem is with
Versions Data Deleted 1 &
Retain Only Version 10
why can't I restore the lost files

                You're
backing it up every 2 hours. With retver set to 3, this means you can
only restore to 6 hours ago if the file is changing regularly (3
versions x 2 hours).

                there is no error, just can't find files 4 hours ago in a special folder!
I have lots of folders in F:
and can not find files in F:\INT 4 hours ago, other folders is ok
and the dsm.opt file is all right!
now, I lost all files in F:\INT, but I can't restore them, because it happens for more
than 10 hours before I started to restore them from TSM

other folder is ok

what's wrong, who can help me, thanks
       
       
我在adsm.org上的第一个问题，顺利得到解决
不能恢复数据的原因是backup/restore的 GUI出问题了，出什么问题不知道，只是不能恢复那个时间段数据，日常的数据恢复还是可以用的
解决的办法是使用Cli来完成
命令如下：
>dsmc restore -pitdate=03/02/2008 pittime=09:40:00 F:\public\CELL\INT\ -subdir=yes
命令行功能很强大，以后要多用命令行来完成这些事情
以后记得整理一篇在client上使用的命令行进行备份和恢复的文章出来
