<html><body><p><tt>> From: "Simon Thompson (Research Computing - IT Services)" <br>> <br>> Does anyone know how TSM backups handle XATTRs? </tt><br><br><tt>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. </tt><br><br><br><tt>> Or even other attributes like immutability,</tt><br><br><tt>Immutable files may be backed up and restored as immutable files. Immutability is restored after the data has been restored.</tt><br><br><br><tt>> can you do a synthetic recreate of the TSM HSM tape from backups?</tt><br><br><tt>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.</tt><br><br><tt><br>-Wayne</tt><BR>
