    The update from version 3.1.4 to 3.2.0 causes jobs to take over 2X longer & finish with a warning. I was using TarBZ2 compression and the backup finished in about 216s. After updating the plugin to 3.2.0, the job had a restart, took 519s, and finished with warnings. Excerpt of the end of the log file:

    [30-Sep-2015 04:19:12] 1. Trying to create backup archive …
    [30-Sep-2015 04:19:12] Compressing files as TarBz2. Please be patient, this may take a moment.

    [30-Sep-2015 04:27:43] WARNING: Job finished with warnings in 519 seconds. Please resolve them for correct execution.

    I changed the compression scheme from tar+bz2 to just plain tar, because many of the files are JPG images, which won’t compress much if at all. I manually ran the job and it completed in only 21s with a backup file size growing from 578MB to 650MB, only 12% bigger.

    Hope that’s helpful for anyone.

    Hmmm, in bz2 Compression hase nothing changed in the 3.2 release. What is if you use gz?

    Thanks, it could have been that something changed on the server, but plain tar works so well and so quickly (1/10 the time), that I’m going to leave it on tar. Most of the files are JPG images, which are already compressed, so it’s wasted machine cycles to try to compress them.

    That gives me an idea for your plugin: an option to only compress text files (including code like CSS, PHP, and HTML) and NOT bother trying to compress images, audio, or video (which might exceed server time limits). That would be slick!

    Compression is one think but the exssecive file reades and write will be stay.

    Under v3.2.1 I tested using TarGz, and the archive compressed to 567 MB versus 647 MB with plain Tar, saving about 80 MB. The job time increased from 22s to 57s, which is still OK. It’s much better than the 218s I was getting using TarBz2 under v3.1.4. Even under v3.2.0 using TarBz2 the archive compressed to only 577 MB, so TarGz beats TarBz2 on size as well. Good suggestion to try TarGz. Thanks!
