Re: [Veritas-bu] D2D or Tape Libraries

D2D might require a lot more storage than
you estimate. Think of how often you buy new tapes.
However, that can be mitigated with dedupe
solutions like Data Domain. Also Data Domain offers syncing to an offsite
unit of the same type. Also the big disk array manufacturers due have things
that allow you to sync from one array to another. (However, this is typically
a one off kind of thing – the next sync overwrites the previous one.) You’d
have to pay the offsite vendor for floor space, networking and power though.
Haven’t priced that myself but suspect it wouldn’t be cheaper than tapes. Also
with “permanent” storage on disk as opposed to tape you always take the risk
that the remote storage might die and kill all your backups. Tapes can
degrade but you are far less likely to lose all your offsite tapes at one fell
swoop.

Libraries

Just wanted some views on this....
Been using Tape backups + Robots for years, and only lately
things have been going wrong!
Decisions seem to be made about removing tape backups (maybe
using them for monthly) and going to D2D solutions only.
Anyone got views on this? Pros or cons?
I do not mind D2D but I also like the "feel" of
Tapes and storing them outside a site in a secure safe! Cannot do that with a
EVA System !
Note: D2D is not to go to tape, remains on disk until it
expires.

Simon
