Problems archiving Linux symbolic links on NFS
CentOS (RH lite) 5 with TSM 7.1.4.4 client User called about an archive that keeps aborting/failing with no real details. Sometimes the archive will run for a while and sometimes fail pretty quickly. 04/28/2016 17:39:50 ANS4023E Error processing '/home1': file input/output error 04/28/2016 17:41:30 ANS1999E Archive processing of '/home1/ngandhi/*' stopped. 04/28/2016 17:41:30 ANS4023E Error processing '/home1': file input/output error 04/28/2016 17:56:36 ANS2820E An interrupt has occurred.

The user confirmed this. They also did all kinds of verification that there aren't any problems with the symbolic links or the filesystem. They can't use archsyml=no since these are end-of-semester archiving and if needed, the users would have to have it back the way they left it.

Windows and symbolic links
Windows 2012R2 server TSM 7.1.2.0 client The customer has a drive with a symbolic link off to a UNC share path. When the backup runs it backs up the drive, but does not follow the symbolic link and backup the UNC share. Which is what we really want to accomplish. The FOLLOWSYMBOLIC=YES is ignored in the DSM.OPT file. I know it says *NIX only, but I was hoping. Anybody know of a way to get TSM to follow that symbolic link on the drive?

Re: Windows and symbolic links
You may have already looked at this, but it may be a Windows permission problem. If the System account is running the client, it can only backup local drives. You need an account that has authority to backup non-local drives/shares. George Huebschman (George H.)

TSM 5.3.1 server on windows 2K server. TSM client 5.1.7 on RHEL4-AS. The client has some recursive symbolic links, and whenever the client backs up, the server tries to backup every directory within the sym link, which is infinite and the backup dies. Is there a flag to ignore backups of sym links? I searched the list back a couple of years, one other person asked, but no answer. I also checked the install readme, and it only mentions how to restore an object within a symlink, not to avoid backing then up alltogether. Thanks for your time, Alex

Re: symbolic links
Alex - It is the case that the client OS environment is screwed up, and that the client administrator needs to fix it...which is to say that this is not a TSM problem. (However, the TSM documentation on symbolic links is conflicting: In the Unix client manual it says, During a backup operation, symbolic links are never followed. In IBM Technote 1117280 it says, TSM is designed to backup the symbolic links and their associated object. ... TSM will attempt to follow the link to the actual object.

Re: symbolic links
I added archsymlinkasfile=no to dsm.opt and that seems to fix the problem. So we are good. And yes, TSM linux client I'm using (5.1.7) does follow and backup symlinks by default, so if you've got recursive links, the backup will fail. So the fix is that option. At least that works for us right now.

ANS3008- too many symbolic links/looped symlink definitions
Anyone else seen this yet? I have LPARs running AIX 5.1 ML3, client code 5.1.5.5, server 4.1.9.2 (on AIX 4.3.3.10). When an archive is attempted (with the default of followsymlink=yes) you get this error message in the error.log 01/18/03 05:41:27 ANS3008E Too many symbolic links were detected while resolvi ng name '/usr/HTTPServer/htdocs/en_US/pc_client/pccship/html/en_US/wsmship/html/ en_US/wsmship/html/en_US/wsmship/html/en_US/wsmship/html/en_US/wsmship/html/en_U S/wsmship/html/en_US/wsmship/html/en_US/wsmship/html/en_US/wsmship/html/en_US/ws mship/html/en_US/wsmship/html/en_US/wsmship/html/en_US/wsmship/html/en_US/wsmshi p/html/en_US/wsmship/html/en_US/wsmship/html/en_US/wsmship/html/codebase/taskgui de a ls -al on the problem symlink reveals: lrwxrwxrwx 10 Oct 01 13:40 /usr/websm/html/en_US/wsmship - /usr/websm lrwxrwxrwx 10 Oct 01 13:40 /usr/websm/html/wsmship - /usr/websm lrwxrwxrwx 10 Oct 01 13:40 /usr/websm/pc_client/pccship - /usr/websm which looks like a looping symlink to me. All of our LPARs are like this. Does everyone else's? I was unable to find an APAR on this, but was curious what you all found. thanks! lisa
Symbolic Links
What is the correct way to backup Symbolic links for AIX. TSM server V 4.2.1.11 AIX client V 4.2.1.23 The client wants to backup all the folders pointed by the Link and also restore the folders pointed to by symbolic links. Should I be able to see the link in the Backup GUI ? Thanks Rajesh Oak Outgrown your current e-mail service?

Zosimo, I've been a victim of that also, and on Irix. It can kill your system by filling up the log very fast. The fix is to use client 3.1.0.7 or later and use the switch ARCHSYMLinkasfile No. Otherwise you end up with circular link definitions. We fought that for a year before that client version and switch were released.

how can i exclude this in archive or solve this symbolic liinks. Zosimo - There is EXCLUDE.ARCHIVE; but I would dig into that file system and resolve its problems, as they are unhealty for anything going through that area. Step your way into that problem directory and see what's going on. Richard Sims, BU
