Windows 7: Backup-Images and disk compression

12 Aug 2011   #1

Windows 7 Pro 64bit SP1
Backup-Images and disk compression

What are the +'s & -'s of the two options for the properties on my backup external USB drive ?

Is there any drawback to using the "compress drive" option to increase disk capacity...and...

Should the backup files be indexed or not ?


p.s. can you choose "compress" after the drive contains data or only when the drive is formated and empty ?

I think compressing would slightly slow the access time to the files. I wouldn't do it unless space was at a premium. I'd buy a larger drive rather than compress if space was running out.

Indexing is useful to search the contents of files using the Windows search function. Normally, I would think you would want to search the contents of your ORIGINAL files, not the backups---if you are the type to search file contents and use the Windows search function at all. So you might index the drive that contained originals, but not the drive that contained backups.

Personally: I do not index or compress any of my drives. I do not use Windows search. I never search for file contents. I use a third party tool to search file titles only.
