    One of my backup drives is obviously having problems (Chronosync takes forever to back up and there's no progress -in the end I do a forced quit). This is when performing a bootable backup of OSX and the apps, but strangely when backing up just my user files I'm not having problems.

    So I ran Disk utility and after a while I get the following error message:

    Disk utility stoppred repairing [DISK NAME]
    Live file system is not supported

    What does this mean?

    Data storage units be they HDD or SSD can be defective or become defective. The stored data can become corrupted for a no apparent reason. The best thing to do when you receive any error message is to copy it exactly and do a web search for it. Your disk may have "bad blocks" areas that don't work, that will not stop reading or writing to the other parts. I Suggest you erase, reformat and repair. If you get no errors after that it may be ok for temporary storage but I would not use it for a primary backup. I have scrapped two thumb drives and a 1Gb HHD this year.
