I am having extremely slow backup times with my new set up for backups.
I have an open ticket with tech support but no luck fixing it so far.
What kind of throughput are others getting?
Our set up:
- Windows 2008 R2 Server (production file server)
- Source files located on Directly Attached Storage device that is connected to the same server that is running backup software
- SpectraLogic T50e Tape Library with one LTO-6 tape drive is connected directly to same server that is running backup software (connected using fibre to HBA card on server)
- Backup software is Backup Exec 2012 (new install)
- Trying to back up over 2TB of data located on DAS device
We ran the following testing scenarios:
Note: G drive is the DAS device
#1 Backed up Public and User folders located on G drive to tape.
- This backup was approximately 2.3TB and took 38 hours 19 min to complete.
- According to Backup Exec, the throughput was 1,015 MB/min
#2 Used ITDT program to test the tape drive
- Ran a write test to a tape and was getting 149 MB/sec write speeds
#3 Ran a test backup with Anti-Virus installed on the server
- Backed up G:\Image to Tape
- 172 GB backed up in 1hr 32min 32 sec
- Throughput was 1902 MB/min
#4 Ran a test backup without Anti-Virus installed on the server
- Backed up G:\Image to Tape
- 172 GB backed up in 1 hr 17min 45 sec
- Throughput was 2263 MB/min
#5 Ran a test backup without Anti-Virus installed on server from different source
- Backed up D:\Test to Tape (same files as G:\Image)
- 172 GB backed up in 1 hr 14 min 50 sec
- Throughput was 2352 MB/min
Set up a Disc Storage device using Backup Exec on the D drive of that same server for testing
#6 Ran a test backup to Disc Storage
- Backed up G:\Image to Disc
- 172 GB backed up in 1 hr 7 min 50 sec
- Throughput was 2595 MB/min
#7 Test copying speed from OS (not using backup software)
- Set up a folder D:\Test copy
- Copied G:\Image to D:\Test copy
- 172GB copied in 11 min 13 sec
I am running out of ideas.
