Does anybody know of a project that is doing Storage Migration along the
lines of the Veritas NetBackup Storage Migrator
http://www.veritas.com/products/category/ProductDetail.jhtml?productId=storagemigratorunix
This is basically where seldom used files are transparently moved to
secondary storage and back again if they are needed.
I can think of one method of achieving something along these lines.
Have a script run once a day which would find files that had not been
accessed for x days.
Then move these files to the secondary storage.
Then create a link to the new location.
On the secondary storage you could have another script which looks for
accessed files, and if any have been accessed they could be moved back
to the primary storage.
The sort of setup I'm think of would be where the primary storage is
fast SCSI RAID and the secondary storage is slower/bigger IDE RAID.
So if anybody has any ideas....
