Depends on _WHAT_ software wrote on the tape. If you are reading from 'standard' UNIX style file marks and some variant of tar you can do whatever you want but I wouldn't recommend hopping too many file systems since you'll lose all file metadata.
If you are using some Windows backup software you'll need to use that to dearchive the file sets and either write them back out to the new medium. That's not even considering size packing. WinTAR is CRAP, just use Linux (FYI even Linux to *BSD is problematic due I buffering and link discipline issues plus BSD tar and GNU tar are not always compatible). Whatever you wrote the tape with, read it back with the same across the entire hardware and software stack. Everything else is painful. NEVER use drive's hardware compression unless you have a case of those exact drives. Especially with HP drives. Seriously there be evil evil dragons or even what dragons are afraid of. I've done petabytes worth of this kind of work and it always blows unless your process is as hardware/software agnostic as possible. I also avoid incremental since the rebuild swap media game can go to hell. When I did this in a past life I'd use Linux (our customers were either SGI or Linux centric on injestion). Organized file marks by logical order (ie. one data set folder per mark) an appended a log of the tape write at the END of the tape. This way not stuck in catalog hell and can always compare crc's (in my case used MD5 in and on the logs to validate against corruption). Let's not talk about catalogs... I so hate you Veritas BackupExec. Seriously... I don't miss tapes (or UDO OSARS). -- Sean (mobile) > On Dec 2, 2013, at 3:37 PM, Aemilianus Kehler <zew...@gmail.com> wrote: > > Why can't you read LTO-2, and then just write the accessed data straight to > LTO-6?
