Re: Need ideas for offsite copy of HSM tapes

Synopsis: Want an offsite image of HSM data for DR, but want to avoid
the use of tapes for an onsite backup image.
I would approach it this way: Via dsmmigfs, defined the stub size to be
512 to eliminate leading file data from the stub, to force all files to
be eligible for migration. Employ a relatively low HThreshold value on
the HSM file system, to cause most files to migrate naturally. Prepatory
to daily TSM server administration tasks, schedule a 'dsmmigrate -R' on
the file system, allowing enough time for it to finish. As part of daily
TSM server administration, do Backup Stgpool on the disk & tape stgpools
to which that HSM data migrates, to an appropriate offsite stgpool.
