I'm currently using Arcserve 6.2 w/an Exabyte 10h library backing up 250+GB of data on 8mm dat tapes. I can't get it all in one swoop and I'm adding more data everyday. My NOS is Netware 4.11 but soon will go to 6.0. I'm thinking about going SDLT but am reading a lot of negative things about it. Also thinking about switching to Veritas rather than upgrading to latest Arcserve. Anyone have any good suggestions or experiences you wish to share?
