Easter Backup
Posted: Mon Apr 13, 2009 8:43 am
I got a busy SBS2003 running a 3ware PCI-X card with Raid 5 mirror to create 1.8TB drive setup and a JBOD 1.5TB backup drive. The Data is just over 1TB.
3GB memory server which is actually quite used by Exchange etc., so I am thinking about placing more memory on the mainboard to help applications run smoother.
Well after experimenting with the Drive Image options over the last week, I thought while the business is closed over the Easter period that I test out the backup of 1TB. So, it looked pretty reasonable and had a 'fair' transfer rate , I was creating an volume snapshot and then bit by bit making the backup file.
So I set it off on Friday at 8pm and it finished Sunday at 8pm, took 2 days and has made a 588GB file which is smaller then I was expecting as it was estimating around 800GB. However the next steps have proved to be a problem.
I have got these settings
1:I am backing up the 'partition' and not the 'drive'.
2:Storing it on the same raid card but on a JBOD drive for now.
3:Maximum no Backup sets 25 and 1 image allowed. no other options changed
4:Backup type is "Differentially"
5:Slider is nearer Faster instead of smaller size.
6:Backup "actual data only" and password set with email options.
7:Set as a Weekly schedule for now.
8:I have not tested yet, but will restore cause me problems, not easy to test.
Questions please:-
1: Having the option 1 image allowed, is this suitable or should I have 3-4 images, basically I was hoping it would read over the image and do a compare of the data to see if it is changed, then add the changed data to a new file, but would having the '1' image option overwrite the existing huge file?
2: When the system 'volume snapshots', how does it actually do that with a 1TB drive? where does it put the 1TB of snapshot, that would take some time and create a huge huge file. Does it go in %TEMP%? or specified folder?
3: How can I hide the SMTP mail server passwords in emails?
4: I forced the r-drive program on the server to run again and it failed returned this error message via email and it appeared like it locked up, although there was processor activity. I returned after an 1 hour, still the same and locked up and forced closed, the datafile on the backup had not been touched or no other files created, so is the system reading through the 500GB file to check for changes and was too bogged down, there is no network activity so there is plenty of resources available although I am thinking of raising the memory a bit.

ERROR: Cannot commit (The LAST volume of the multivolume image should be the first to be open)
Simply put, is R-Drive suitable for very large volumes?
