    Do you have 2.5TB of space to spare on disk?

    You could create a "virtual" tape drive and save to it. After that save, the contents can also be copied to a physical tape.

    But it might depend on why you want an on-line copy. Are you expecting to restore directly from the on-line copy? If so, what are the object types and sizes of the three largest objects in the library? (Three is enough to give use a general feeling about the library structure.  There might be useful suggestions for different structures.)

    Yes, on-line copy is for fast emergrncy recovery. The 95% of the objects is PF and LF,we have few *DTAARA too. Three largest has more than 100GB. The problem is that the library is growing all the time. In January it has 1,5TB now it has 2.0TB so we are looking for solution that can handle this. I think the VTL will be good, but if You have another solution feel free to tell me :)

    If the system is growing that fast you most likely will be adding more disk on a regular basis.. Not knowing what type of business and the number of transactions are causing that kind of rapid growth you may want to consider cloud services.. Also depending on the length of time it takes to backup / restore, and if these are done in a restricted state or done with a save while active option, you may leave records unaccounted for. The current system I work on has almost 20 years of manufacturing data for numerous divisions and our WRKSYSSTS shoes an AUX ASP of 1986 g and only % 55.1492 used.

    @ToddN2000 I work in bank. We are making backup twice a Day during end of Day processing. Our main library now has 2.0TB and it growing fast. backup takes ~ 1,5 hour but we are making it with *SYNCLIB so it takes 6-8 min to reach checkpoint. We are making backup in normal working state. No~w we have ~3900g and ~60% used. Today i have configured and tested VTL and it works fine :) So many thanks for solution :)

    @Splat *SAVF max size is 2.17TB and this is the problem :)

    I assume this is a new application (rather than one that has recently started growing). I was going to suggest looking at purge options to see if it could slow the rate of growth, but if it is a bank then that probably isn't an option for at least 5 yrs (those are the rules in Oz - yours might be different). So, growing at 0.5TB in 4 months and assuming a requirement to keep 5 yrs history equals 7.5TB minimum (more if the business grows) and a backup time of nearly 6 hrs a day. VTL buys you enough time to take a serious look at your file structures to see if you can't organise things a bit better.
