Hi there,
Sorry to post another 'my system is running slow' query...but I really need your help and I'm keen to know what others are doing.
Brief history:
We used to use a Veeam Backup and replicate to protect our VM's. At the time Veeam could not write to tape, so we used to fire a backup exec job to push the resultant Veeam full backup file to tape. Our few physical servers would be backed via Backup Exec(2010 R2). We needed to upgrade our ageing HW and also wanted a single supplier solution.
...after much research, along cam Symantec BUE 2014, and then BUE15 (which we had to upgrade to due to a bug in BUE2014 that was fixed in BUE15)
History lesson over, now on to my problem.
I've had to spend every night nursing my BUE2014 backups for the last 5 months. I have had countless calls logged with support for a variety of issues and can only assume I'm one of VERY few customers who use BUE 15 in this way, that is, create backup jobs on a CASO server, run jobs on a primary MMS server and then duplicate the jobs to a secondary MMS server. We're using deduplicated disk storage that is local to the MMS servers. The primary MMS server also has a Dell TL2000 dual drive LTO4 tape library and our backup definitions are to run full backups at 18:00 on a Friday and Incremental jobs at 23:00 every 1 day. Further, the definition has three additional stages: 1. Duplicate the full backup to the secondary MMS server; 2. Duplicate the incremental backup to the secondary MMS server and; 3. duplicate the full backup to Tape.
...the idea being that we'll have deduplicate backups duplicated to two MMS servers (that are physically seperate from one another), but also a copy on Tape that is fully 'hydrated', e.g., not in a deduplicated state.
Each step of the above has the verify option enabled and most of my backup jobs are VMDK based (VMware 5.5). I have not installed the agent purely because few of my servers will require me to restore files/folders directly to them, e.g., I'm happy to restore to the CASO server and manually move a restored file to the correct location.
My backups are slow....I'm performing 4 concurrent jobs and at the moment I'm nearly 3 days into a full backup. The MMS servers are new; both have 12TB of disk space, plenty of CPU and 32GB of RAM. Using performance monitor I can see that CPU rarely gets above 30%, network usage about 25% and memory usage rarely hits 20% of used RAM. My disks are also idle for most of the time. These kind of performance stats would lead me to think I could increase the concurrent operations, but doing so slows down the 4 existing jobs. As I type I've actually made the decision to disabled the tape drive and will run these jobs after the 'disk' based elements have completed. I'm using 5TB out of 12TB and have noticed that windows is reporting the disk is heavily fragmented, e.g., 83%. Surely if fragmentation was an issue I'd see this in the performance monitoring stats, e.g., disk queues and such like? Also, Windows Server 2012 R2 is configured for weekly disk defrags. I have no AV software installed.
Veeam/Backup Exec 2010 managed....it just ran on old hardware and was two solutions rather than one. However I am beginning to think I've wasted my money on BUE15. I'm tired of watching my backups and tweaking things to make it work.
What sort of schedules do others use......I'm I doing tool much here? Should I opt for more incrementals and fewer full backups? (Veeam had forever incrementals.....I only ever completed one full backup).
Thanks in advance and sorry for the long post...I'm tired and stressed and hoping someone will pitty me and moreover give me a snippet of information that's going to change my life!
