What is the best way to store a large amount of text in a table in SQL server?
Is varchar(max) reliable?

If you want to store large amounts of text in a SQL database, then you want to use either a varchar(max) or a nvarchar(max) column to store that data. In case you don't know the difference, nvarchar will support Unicode characters.
The MEDIUMTEXT data object is useful for storing larger text strings like white papers, books, and code backup. These data objects can be as large as 16 MB (expressed as 2^24 -1) or 16,777,215 characters and require 3 bytes of overhead storage.
The most recommended and best option is to have a STANDBY server, restore the backup of the production database on that server, and then run the DBCC command. If the consistency checks run ok on the standby database, the production database should be ok as it is the source of the standby.
n defines the string length and can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes (2 GB). DECLARE @longText varchar(max); SET @longText = REPLICATE('X', 8000); SET @longText = @longText + REPLICATE('X', 8000); SELECT DATALENGTH(@longText); Returns 16 K of characters.
In SQL 2005 and higher, VARCHAR(MAX) is indeed the preferred method. The TEXT type is still available, but primarily for backward compatibility with SQL 2000 and lower.
