A) Did you have a ‘failed backup’ just prior to this slowing down? The first backup after one that failed or was cancelled may appear to be running very slowly, while Time Machine "recovers" the partial "in.Progress" file from the previous one. Give it a long time before deciding there's a problem. B) The first backup after removing certain exclusions, especially System Folders and/or Applications, can appear to be extremely slow, as they involve tens of thousands of mostly very small files. It may also seem to report that it’s reached the amount to be backed-up, but then the amount will increase (often very slowly). C) Did you notice if Spotlight was indexing when the slowdowns started? Exclude it from Spotlight, via System Preferences > Spotlight > Privacy. Spotlight might decide to start indexing the backup volume while the backup is in progress, causing a huge slowdown in backup speed (doubling or even quadrupling the required time, not to mention sucking up CPU time). The solution? Exclude all backup volumes, and remember that after erasing a drive, you’ll have to re-exclude it; Spotlight has the temerity to forget about the excluded volume once it’s erased, even if the name remains the same. D) If you’re using the Directory Protection feature of Tech Tool Pro, exclude your Time Machine volume from it. It can slow your backups down significantly, and it won’t help fix a problem there, anyway. In addition, you probably want to exclude its files from Time Machine backups, as they may cause large backups. > > The TC has 270GB of space available, so I don't see that as an issue. > > Any suggestions as to what the cause of slowness might be?
