Adding Compression to an Uncompressed Media Set

Recommended Posts

I assume it is OK to switch to Compression-On with a backup media set that has been running for some time with no compression; it just means that subsequent backups will be compressed, correct? No further disadvantages or advantages?


How much compression can one count on for a typical root directory backup in percentage points? Just curious. I should have turned it on from the get go. Thanks.

any thoughts about how much, percentagewise, compression saves in terms of file space?


While Robin can give an average of a typical hard drive, compression depends entirely on the data being compressed.


Got a volume full of .mp3 files? You won't save any space.

Got a volume full of .tiff files? You're likely to save quite a lot.

.txt? Good compression values. .zip? Poor.


Only you know.
