AW: Subfile Backup Experience
During testing i realized, that i can only restore files (with subbackup-parts) to with i have full NT access rights. (I am working local as administrator) Typicaly i do not have that rights for private (pst) files. Is this right?

Re: Subfile Backup Experience
That sounds good. I have read the docs about Subfilebackup and have 2 more questions. what about the TESTFLAG Takeownership for dsm.opt is it still in devolpment, does it work,? (i'm a little confused about the name testflag) I'm aware about the problem moving the rebuild file from the tsmtmp directory to its original location. >> Sorry I don't know anything about that what it is? We've had no problems with backups or RESTORES using subfilebackup. how you should handle the client cache? Should it be excluded from normal backup? Are the files in it automaticaly deleted after some time or does the tsm client wait until the cache size limit is reached? In my testenvironment i have many many small files in my cache dir, although there are only little changes. >> Yes, the client cache should be excluded from backups. It says that somewhere in the white paper, I think. As far as I can tell, stuff is only purged from the cache when you hit the cache size limit. ( BTW, if you only turn on .pst files for subfile backups, what are all those files in your cache?) But the cache is only used during backup, not restores. I tried everything I could think of to damage the cache, including blowing it away entirely. If you hurt it, it just means that the next time you do a backup, TSM starts over with "full" file backup of all files, just like the first time you ever did it. So I haven't found any way to break it.

That sounds good. I have read the docs about Subfilebackup and have 2 more questions. what about the TESTFLAG Takeownership for dsm.opt is it still in devolpment, does it work,? (i'm a little confused about the name testflag) I'm aware about the problem moving the rebuild file from the tsmtmp directory to its original location. how you should handle the client cache? Should it be excluded from normal backup? Are the files in it automaticaly deleted after some time or does the tsm client wait until the cache size limit is reached? In my testenvironment i have many many small files in my cache dir, although there are only little changes.

Re: Subfile Backup Experience
Hi again Stefan. With subfiles you will need to do a reconciliatory backup (full backup) each week. If your LAN can support this, then subfiles will really help reduce the differential percentage based on automatically selecting block, byte or file level adaptive differencing. Be careful that the cache file is not touched by an operator, and make sure to run a full backup once a week, and you'll be fine.

Re: Subfile Backup Experience
One of our TSM servers backs up approx. 350 Wintel desktops nightly, plus about 30 Windows & UNIX servers. Our users keep their .pst files on their desktops, rather than on the fileserver. Our daily load has been growing steadily, doubling every year, and I determined that the biggest chunk of the growth was those .pst files. I turned on subfile backup last Nov. 1 for all our desktops via a client option set. I let it grab everything, not just the .pst files, and it has dropped my daily load by about 30%! Haven't had ANY problem with it. I tested extensively on .pst files of my own, and I haven't been able to break it. And we have successfully done 4 bare-metal restores since implementing it. I'm a happy camper! TSM 4.1.3 for AIX; all TSM clients are 4.2.0; desktops are WIn2K PRO SP1 & SP2.
