restored deleted data on subversion

[wrodrigues201]

Hello,

Our subversion (1.4.3-r23084 on windows 2003) was holding around 1.6 TB 
of data and one user has accidentally deleted a directory of 1 TB. I 
have done a svn export from the previous version and have the data. Do I 
have to add and again commit this data ? Will it use up 1 TB of disk 
space on the svn server ? Is there any way i can restore the data from 
the previous version without using up 1 TB of disk space ?

Thanks in advance.
