My new Gdrive gives me an error when executing a Time Machine backup: "Unable to complete backup. An error occurred while creating the backup folder." It only works after a reboot. How can I fix this?

    Look at C2 in the first article. Also make sure the disk is formatted properly.

    If you have more than one user account, these instructions must be carried out as an administrator.

    Launch the Console application in any of the following ways:

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select

    View Show Log List

    from the menu bar.


    Enter the word "Starting" (without the quotes) in the String Matching text field. You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard." Note the timestamp of the last such message. Clear the text field and scroll back in the log to that time. Select the messages timestamped from then until the end of the backup, or the end of the log if that's not clear. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.

    If there are runs of repeated messages, post only one example of each. Don't post many repetitions of the same message.

    When posting a log extract, be selective. Don't post more than is requested.

    Please do not indiscriminately dump thousands of lines from the log into this discussion.


    Some personal information, such as the names of your files, may be included — anonymize before posting.

    I have the same problem at two places. At home and at work. The same system (Lion) the same external drive: G-Drive 2Tb.


    Here are messages from console concerning backup failure.

    First backup works but none after.

    Partitions in two subdisks and reformating don't help.

    Please, M. Davis, have a look.
