Thanks for the info. What sort of backup transfer rates are you getting (from your clients to the USB-3 backup disk)?
I back up over a 1Gb/s network to a USB2.0 device and get 42MB/s backup. I also get 25MB/s restore (restoring from USB2.0 to a directly-connected SSD), so I'd expect better for USB-3 without a network bottleneck (perhaps Forgive me if it's a silly question, but is the USB-3 drive definitely connected to a USB-3 (blue, or "SS"-labelled) USB port? Picking some very (very) arbitrary figures, I'd expect your results to be around 100MB/s backup and 50MB/s restore according to the set-up you describe. -- Graham ________________________________ From: Lionel PLASSE Sent: 23 December 2021 13:53 To: bacula-users@lists.sourceforge.net <bacula-users@lists.sourceforge.net> Cc: Graham Sparks <g...@hotmail.co.uk> Subject: RE: Restore experience report Yes you're right, i explain the situation The targeted disk for restauration is a SATA-II directly connected to the mother board with a SATA cable nor USB nor RAID but directly to the SATA controller, it's a small extension to the front of the computer. The backup media volumes are usb disk volume and stored on USB-3 disks . This USB disk (XFS formatted) contains the volume file and all bsr and backup of bacula conf . It is automatically mounted by linux when plugged on the storage dir . One USB disk file with one media volume file. All my dayly jobs (9jobs for 9 clients) are run on the volume every day : Incremental from Mon to Thu and Differental the Friday and each first Friday it is a Full instead of Diff Bacula-dir sd fd and mariadb are on the same server I restore on the same machine from the USB volumes to the hotplugged SATA disk. I thought that because of all the restauration process has been made on the same server it will be faster ... ------------------ De : Graham Sparks <g...@hotmail.co.uk> Envoyé : jeudi 23 décembre 2021 14:00 À : bacula-users@lists.sourceforge.net Objet : Re: Restore experience report Hi, I think a little more info is needed to narrow down whether or not these restore transfer figures are slow in this particular case. How is the hotplug SATA-II restore disk connected (RAID controller, or USB), and is it connected to the bacula server directly, or through a client? Also, where/how is the backup data stored? -- Graham ________________________________________ From: Lionel PLASSE Sent: 23 December 2021 09:35 To: mailto:bacula-users@lists.sourceforge.net <mailto:bacula-users@lists.sourceforge.net> Subject: [Bacula-users] Restore experience report Hello, I just post my full restore experience for performance studying purpose. I use Bacula 9.6.6.3 & - 10.3.30-MariaDB on a Debian 11 buster x64 i5-2320 3Ghz CPU - 32GB ram For the 1st restoration (by baculum wizard interface) FULL on Western Digital Blue 500Gb (DOS partition table and NTFS partition) : Where: /srv Replace: Never Start time: 22-déc.-2021 09:19:43 End time: 22-déc.-2021 12:04:47 Elapsed time: 2 hours 45 mins 4 secs Files Expected: 202,006 Files Restored: 202,027 Bytes Restored: 32,650,343,324 (32.65 GB) Rate: 3296.7 KB/s FD Errors: 0 FD termination status: OK SD termination status: OK Termination: Restore OK ~2h25 of restoration cause there was 3 volumes in use for restoration (FULL/DIFF&INCR) and I didn't noticed the request of changing volume. The rate is a bit slow I think. (max rate was 5 MB/s) I'm performing now an other full resto with a greater size of restoration on a 4TB Westerndigital Violet (GPT & NTFS partition) The rate is curently 10.62 MB/s Feed back the result this afternoon (I hope) What do you think of the performance, is it possible to do better ? knowing that the restored disk is on a hotplug SATA II interface. _______________________________________________ Bacula-users mailing list mailto:Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
