Lisa,

All the filesystems within the rootvg are backed up with a mksysb as long
as they are not explicit excluded from rthe mksysb. In general AIX does not
delete (major) files on reboot as other UNIX's do ( eg /tmp ).
This is how we do the restore of an AIX machine :
1) restore mksysb
2) restore "OS-definitions" via TSM ( rootvg filesystems eg. /etc ) ( TSM
Client already restored by mksysb )
3) restore filesystems (non rootvg) via TSM
4) restore application-data ( DBs eg. ORACLE,SAPDB, MSSQL etc ) via TDP
Agents in necessary.

Step 2) depends on the time-difference between the mksysb and the last
config changes of AIX. Should not be necessary if you make a mksysb after
every config change , as all of the sysadmins do :-)

So what we do, we dont exclude files from the rootvg in the TSM backup (
AIX-OS is not really need much space ) but we exclude lots of temporary
application files. We think that at this point we can find a lot of
temporary data (eg. SAP rollfiles ).Of cause you have to know your
application / Datebase very well, so that you dont exclude a file by
mistake.

Subject:  AIX 4.3.3 list of excludable files & filesystems


Has anyone ever compiled a list of files and/or file systems that can be
excluded from backup either because they are dynamically created by the OS
at
reboot/syncvg etc
or because they are included in a mksysb?
