AIX

When I use tsm command: archive -subdir=yes /dir1/
to backup file system: /dir1

After I delete the contents under /dir1 and recovery it from TSM backup,

retrieve /dir1/

I found the link breaked. Such as:

Before:

ls -l

lrwxrwxrwx 1 abc develop 8 Apr 28 16:04 bin -> bin.abc

After:
ls -l

drwxr-xr-x 2 abc develop 256 Nov 13 15:39 bin
drwxr-xr-x 2 abc develop 256 Nov 13 15:39 bin.abc

How to backup and recovery this kind of filesystem by TSM?

IIRC TSM defaults to following the links and therefore archiving the file. Thus you get the file after recovery. You need to set ARCHSYMLINKASFILE=NO to archive (and retrieve) a link as link.
