TSM capture XATTRs and ACLs in an opaque "blob" using gpfs_fgetattrs. Unfortunately, TSM stores the opaque blob with the file data. Changes to the blob require the data to be backed up again. > Or even other attributes like immutability, Immutable files may be backed up and restored as immutable files. Immutability is restored after the data has been restored. > can you do a synthetic recreate of the TSM HSM tape from backups? TSM stores data from backups and data from HSM in different pools. A file that is both HSM'ed and backed up will have at least two copies of data off-line. I suspect that losing a tape from the HSM pool will have no effect on the backup pool, but you should verify that with someone from TSM. -Wayne
