SFS Restore?
I've never worked with SFS before. The SFS was designed and put into 24x7 production use circa 1996. There are few trails to follow. Presently there is a daily backup of the system plus weekly DDR's of the volumes. Due to production I cannot shutdown for much more time than the backup takes. I need to restore or somehow obtain a program (deleted by a programmer), and only that file. The manuals I have found are not too clear regarding recovery/restore of SFS. Can one file be easily obtained from a backup? Phil
Re: SFS Restore?
You said your weekly backups are done with DDR, you didn't mention what method you use for your daily backups. If you only have DDR backups, then there is no easy way to get one (or any) individual file(s) restored ... you have to restore the DDR for *all* minidisks that make up the FilePool.

Re: SFS Restore?
The daily backup is created from the SFS system via backup. Which since it has no parameters associated with it, I am assuming that everything is backed up.

Re: SFS Restore?
You'd need to restore the DDR backup to a new filepool user (with exactly the same minidisk configuration, for example userid NEWSFS). After the restore, link to the restored NEWSFS 191 and - RENAME oldSFS DMSPARMS fm NEWSFS = = - change the filepool ID in NEWSFS DMSPARMS to e.g. TEMPSFS - RENAME oldfpool POOLDEF fm TEMPSFS POOLDEF = Release and DEATCH the NEWSFS 119 and start NEWSFS up. Then you can isseu DIRLIST TEMPSFS:someuserid. But, as I wrote earlier today: DDR backups taken while SFS runs, may yield a corrupted SFS after the restore. If you don't want to spend money on a decent backup product (like IBM's IBM Backup and Restore Manager or CA's VM:Backup), you should better use FILEPOOL BACKUP as backup method: - no extra SW license - can run while SFS is active (better: SFS must run during the backup) - you can restore one or more files from the backup medium. (memory is a bit rusty, it may be FILEPOOL UNLOAD instead of FILEPOOL BACKUP to be able to restore selected files; the SFS admin manual will guide you to the details.) 2008/12/23 Phillip Parmelee parme...@us.ibm.com: I've never worked with SFS before.

Re: SFS Restore?
If your daily SFS backups were created by the FILEPOOL BACKUP command you could use FILEPOOL FILELOAD to restore individual files. If the daily SFS backup was created by FILEPOOL UNLOAD, you can use FILEPOOL RELOAD to restore individual files.

Re: SFS Restore?
Unless you have a product or process that does file level backups (look in the list of file pool administrators for clues) you are going to be in trouble. Physical backups of a running SFS server are generally not of much use.

Re: SFS Restore?
Your assumption may be faint. You issue BACKUP on the SFS server's console (or CP SEND VMSERVx BACKAUP, what is the same) do you?. If this is the case, you only have a backup of the SFS control data (that is, who is enrolled, which GRANTs are given, etc), but **not** of the data residing in these SFS files. 2008/12/23 Phillip Parmelee parme...@us.ibm.com: The daily backup is created from the SFS system via backup.

Re: SFS Restore?
Your best bet at restoration is to do as Kris suggests. I would not, under any circumstances, restore directly to the corrupted file pool from the DDR backup unless it was taken while the file pool was down and before the corruption occurred. Even then, you would back level all files and catalog entries that were updated between the time of the backup and the restore. Since we are an active 24 hours per day shop, we can never use DDR as a potential backup process for our SFS. We had a problem a few years ago with a corrupted catalog block that required the help of the support center. The block was corrupted during a data center move and the corruption caused the system to crash whenever any file whose catalog entry was in the corrupted block was referenced. Getting past this one required that we send a copy of the catalog disk to the support center so that they could craft a zap to bypass the bad entries. It took two tries to get it right because the first zap just handled the failing file at the time of the crashes, all of which were during attempts to backup the same file. After bypassing the bad block we did a filepool unload, created an all new filepool, and did a filepool reload to the new location/disks. In short, if you open a PMR with the support center, they may be able to perform some magic for you. Without them, we would have lost several days of updates instead of just the 19 files that were identified as having entries in the corrupted block.
