My 25G repository filled 75G of dump then bailed out because of lack of disk space, so I'd like to know how much more space do I need to buy. Before you go telling me "get yourself a 1T external disk" I must underline that we have heaps of policies for requesting storage, for using storage, for NAS and SAN and RAID and whatnot so I really need to know how much I should ask for.

Your dump file will be considerably smaller if you export with --deltas.

I would expect the size of the equivalent fsfs repository to be an
upper bound on the size of the resulting --deltas dump file. At least
for the repositories I have lying around, this appears to be the case.
