Re: Full Incremental Rotations

Abrian,
concernin WEBSM:
Problem DB growing rapidly when backup or archiving /usr. Operations
such as backup, archive and delete archive can fail with errors ANS3008E
; Too many symbolic links or ANS5023E Not enough memory Cause recursive
symlinks on circular linked directories of WEBSM product Solution A
deeper look into /usr shows a link called /usr/websm/html/en_US/wsmship/
that points to /usr/websm.
These files are from WEBSM product and the structure under /usr is
normal (more that 40 levels of subdirectories with wsmship symbolic
link). TSM follows the link and puts the operation in a loop and the
result is that TSM is inspecting more objects than exists and the
operation can abort due to many links or not enough memory. The solution
is to use archsymlinkasfile no in dsm.opt for archive operations and
exclude lines for backup operations. For example :
exclude /usr/websm/html/en_US/wsmship/*

Hi There,
I want to ensure I am implementing the best possible strategy for TSM
backups.
Has anyone implemented this successfully as described in the
Full-Incremental Rotations Using IBM Tivoli Storage Manager field
guide
from IBM.
I am using a copy storage pool , and perform a full backup weekly, and
incrementals during the week. In addition I do an archive on the last
Sunday of each month. All AIX.
Would this constitute best practice.
Another side issue - Has anyone encountered recursive backing up of
linked
directories in AIX. I have a directory called websm that seems to go
into
an endless loop.
Any ideas how to rid of this error with out excluding the said
directory.
Regards
Adrian Compton
