H.Pralow Posted July 13, 2016 Report Share Posted July 13, 2016 Hello, execution time for backups thru Linux clients is very long. I have noticed this problem for a long time but finally made up my mind to open a topic about it in the forum. These are the simple facts: - 12.07.16 23:03:09: Copying www on dev7 12.07.16 23:03:09: No files need to be copied 13.07.16 01:25:56: Snapshot stored, 772 MB 13.07.16 01:26:11: Comparing www on dev7 13.07.16 01:26:59: Execution completed successfully Duration: 02:23:49 (02:16:46 idle/loading/preparing) As you can see even if no files needed to be copied, the backup with this Linux box takes nearly 2 and a half hours where copying and comparing appearently only take a few minutes. It gets worse when there are actually files to copy. Is there a way to speed the execution up to mopderate speed so that backing up Linux boxes doesn't hog my nightly backup schedule? Linux client is 9.5.0.113 OS of the Linux box is 3.13.0-30-generic #55-Ubuntu SMP Fri Jul 4 21:40:53 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Although this paricular client box (dev7) seems somehow extreme other Linux clients in my nightly backup plan are slow as well: - 12.07.16 22:06:17: Copying www on dev5 12.07.16 22:44:12: Snapshot stored, 373 MB 12.07.16 22:44:26: Comparing www on dev5 12.07.16 22:45:17: Execution completed successfully Completed: 22 files, 281,5 MB Performance: 234,6 MB/minute (146,8 copy, 582,4 compare) Duration: 00:39:00 (00:36:36 idle/loading/preparing) Here 36 of 39 minutes are spent idling/load/preparing and I assume, most of the time is needed to store the snapshot. Any idea to speed things up? Quote Link to comment Share on other sites More sharing options...
prubin Posted June 5, 2023 Report Share Posted June 5, 2023 Wow 6 years and no answer. I have noticed this issue for years also. I too finally got tired enough of it to look for an answer. The performance to windows clients is usually about 1900 MB/s and to Linux clients is 50 MB/s essentially 40 to 1. That seems excessive.
