How long does it take to Zip a folder
of this size (appx. 100,000 files)?
how long is a piece of string? 🙂
that depends on the specifications of the computer and the type of data.
is it safe to maintain Zip archives
perfectly safe, ZIP archives don’t deteriorate 🙂
in fact, many backup programs use ZIP compression.
Difficult to answer because it depends on the contents of those sites. A site with lots of JPG images will probably compress faster but result in bigger files since there isn’t much left to compress. Sites with lots of sources and text files will take a bit longer because they’re giving a better compression rate. The speed of your computer, number of processors, speed of the hard disk, amount of free disk space and lots of other factors will eat away your time.
But to get an indication, how long would it take to copy those folders to another location on the same disk? Disk access tends to be the most time-consuming action with compression.
If you ask me, go ZIP it all, get some coffee, wait for it to cool down before drinking and then look if it’s done. In the worst case, you’re going to need a second cup of coffee…
exactly what I was saying to you …
I use :
zip (low compression) for low importance stuff and for sending to newbies (better than no compression)
rar (middle compression) for important stuff in a direct network or straigt on a media support … (network, media supports)
7z (high compression) when I want it highly compressed to put online and I have time to wait to upload faster with less bandwith … (internet mostly)
