Fine, so you have a 10 MBit link across the "street" in the budget but
nothing to buy decent server hardware? 4TB (just to be around where you
expect to be after 6 months or so) per year means an average MBit per
second ... on a second thought, the 10 MBit will probably not be enough
to satisfy peak times.
Who made that mirror proposal and where is your PITR capable backup? I
once saved a company by doing PITR. They ran an Oracle database on two
software mirrored Raid5 systems ... and the application was
misconfigured and deleted too much data (way too much).
