Re: [BackupPC-users] 18 hour incremental backups?
Hi, Boris HUISGEN wrote on 2011-03-02 15:53:10 +0100 [Re: [BackupPC-users] 18 hour incremental backups?]: The compression is disabled (level 0 = no compression) just for the archives: that's complete nonsense. What *should* be disabled is top-posting. Level 0 means full backup, not compression disabled. And disabled compression would usually not make the backups slower, not by orders of magnitude in any case. In fact, if there are a lot of files that are not yet to be found in the pool, disabling compression should make the backup run *faster*. Le 28/02/11 18:09, Rob Morin a écrit : Hello all?

[I hope you've solved the problem in the mean time, but I thought I'd add something for the benefit of anyone finding this in the archives. If you found out what the problem was, you could share your results.] Well, you see that it *is* the home dir that is taking 17.5 of 19 hours, and you seem to be transferring 28 GB in total, so I'd guess there are a lot of changes. In fact, the next incremental backup, based on the same full backup, ran significantly faster. You could look into the XferLOG for that backup to get an idea of what was actually happening (lots of small temporary files?).
