jamesiporter Posted April 10, 2009 Report Share Posted April 10, 2009 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. Quote Link to comment Share on other sites More sharing options...
Mayoff Posted April 11, 2009 Report Share Posted April 11, 2009 you can turn it on at any time. Compression depends on your data type. Quote Link to comment Share on other sites More sharing options...
jamesiporter Posted April 11, 2009 Author Report Share Posted April 11, 2009 Great. Thanks. BTW, any thoughts about how much, percentagewise, compression saves in terms of file space? (a normal root directory of eg 150 GB) Quote Link to comment Share on other sites More sharing options...
Mayoff Posted April 11, 2009 Report Share Posted April 11, 2009 maybe 30% on average. Quote Link to comment Share on other sites More sharing options...
CallMeDave Posted April 11, 2009 Report Share Posted April 11, 2009 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. Dave Quote Link to comment Share on other sites More sharing options...
