Dealing With De-Dupe Doubts: Page 3 of 3

Besides not caring about whether their vendors are exaggerating, neither Paige nor Jeffrey have any complaints about the speed at which de-duplicated data can be accessed or restored either.

Bottom line? The world of data de-duplication is young enough that no one appears to care about product-selling hyperbole. Apparently, the end result is sufficiently dramatic to erase any bad feeling that may come from supplier braggadocio.

Still, caveat emptor. "Full volume backup data will always have the largest amount of de-duplication because every time you backup you are backing up much of the same data over and over again," says one industry analyst, who asked not to be named. "It is this data set that most of the vendors claim their ratios." In reality, he notes, most users get a 2:1 or 3:1 ratio on incremental backups.
