Hello

 

Normally my backups take about 10 minutes, but since last week they take up to 5 hours.

I have this little app "LogViewer for Time Machine" which extracts relevant information

from the log. On 7/12 I got this report:

 

04:28:36 - Starting manual backup

04:28:37 - Backing up to: /Volumes/MyBook/Backups.backupdb

04:28:41 - Using file event preflight for Macintosh HD

04:36:51 - Post-back up thinning complete: 1 expired backups removed

04:36:51 - Backup completed successfully.

 

Everything looks normal. A few days later I got the following report:

 

02:01:14 - Starting manual backup

02:01:20 - Backing up to: /Volumes/MyBook/Backups.backupdb

02:01:43 - Using file event preflight for Macintosh HD

04:41:08 - Using file event preflight for Macintosh HD

04:41:08 - Will copy (7 bytes) from Macintosh HD

04:41:08 - Found 21 files (7 bytes) needing backup

04:41:08 - 1.55 GB required (including padding), 299.5 GB available

04:42:26 - Copied 791 files (2 KB) from volume Macintosh HD.

04:42:40 - Created new backup: 2013-12-12-044227

04:42:43 - Starting post-backup thinning

04:57:40 - Deleted /Volumes/MyBook/Backups.backupdb/uome’s iMac/2013-11-12-030726 (375.1 MB)

04:57:40 - Post-back up thinning complete: 1 expired backups removed

04:57:55 - Backup completed successfully.

 

It took three hours.

- How can 21 files have a size of 7 bytes?

- How can 791 files have a size of 2KB?

Is this OK? Or what is happening here?

Many thanks.

    Did you update or upgrade OS lately?

    Did you install any scheduler for TimeMachine (like TimeMachineScheduler) or did you change the TM schedule with Terminal commands?

    Did you change the TM disk?

    Download   Etrecheck.app   from www.etresoft.com, it produces a list and copy that list here.

    In the meantime you can read all about TM on the internet    http://pondini.org/OSX/Home.html   

    of the late Pondini, which is still in the air, luckily.

    OK, this helps.

    answers to your list in order of list:

    -  HPTrap Monitor: yes you can delete this folder; this will not really delete all remnants of this TrapMonitor, but OSX will no longer try to start it .

    com.apple.coresymbolicationd.plist : this means only that it is not started while it was not requested yet by the system, do not touch it.

    -  same for the next four.

    Now to the rest:

    Remove all four entries from the   SystemPreferences/Users&Groups/LoginItems tab:    remove with the minus sign underneath. (this will not uninstall just prevent them from running at startup).

    Restart the computer, these apps are not running now.

    1. Uninstall WesternDigital app(s), absolutely necessary, if you do not find the uninstaller do the following:

    Go to   Macintosh HD/Library/LaunchDaemons/   delete  the   com.wdc....  and the  com.westerndigital.....

    In Applications or Utilities drag all WD apps to the Trashbin

    In   MacintoshHD/Library/ApplicationSupport/   delete all WesternDigital folders.

    2. I propose to uninstall    Trackball,  MacGameStore, and MenubarRearranger. You will probably not miss them.

    Further remarks:

    a.  In InternetPlugins:

    you can delete the AdobePDFViewer plugins, not needed.

    there are two Flasplayer plugins normally.

    b.   ... longer list of old apps deleted...   the wording is not very precise in the etrecheck list, please post the rest also.

    c.   TimeMachine:

    this is not absolute, read the disclaimer. Maybe you exclude the Bootcamp partition from TM in the TM settings, and you can use Winclone to backup your windows partition separately.

    As to your remark in blue: a TM backup is just a sort of cumulative method, you have all or nothing: this is the most fantastic method of making backups !!!! TM condenses on the way forward in time. Read a very good expose on   http://pondini.org/OSX/Home.html

    OK, restart and make a new etrecheck list.

    You can move the Director.... to a backupfolder somewhere. Maybe you need that later.

    Leave the other two alone.
