sql server - Estimate size of restored DB -

-

the amount of free space on machine limited, , i'd know how many dbs can fit on before restoring them.

so given .bak file, how can estimate how big restored database on sql server be?

this output:

restore filelistonly disk = 'c:\path\file.bak';

has size column (in bytes). can perform math extrapolate there, example let's results in column are:

3211264  802816

these in bytes, , expressed in kb (at least how windows explorer exposes it) be:

3211264 + 802816) / 1024 = 3,136 kb

and in mb be:

3211264 + 802816) / 1024 / 1024.0 = 3.0625 mb

you may want sum of whole column, or may want restore ... move , place different files on different drives if have ability so, in case you'll want consider different files separately.
