How to accelerate backup for a BIG Files servers and SQL servers.
I have 3 very big fileserver, more than one billions of files.
Presently we using the MS-Windows policies to backup'em. I was reading that I could use the FLASHBACK policie (block level) for that kind of file server.
So if i'm using this kind of policie, should I use the FLASHBACK or the FLASHBACK-WINDOWS policie if my server is a windows 2008?
I dont fully understand the difference between MS-Windows, Flashbackup, Flashbackup-Windows.
We using flashbackup-windows to backup our VM on ESX server.
thanks
Flashbackup is for Unix
Flashbackup-Windows is for flashbackup policies on Windows Clients
MS-Windows is a standard Windows backup
Flashbackup and Flashbackup-Windows do raw device backups - they tend to be very fast as they back up at block level and backup the entire drive
So if you have a 50TB drive with 15 TB used you backup will be 50TB!
You can however restore single file data from these backups - I would advise having a moderate fragment size for you storage unit - say 5000MB - so that when seeking a single file from the backup it can be located easily
Also test restores from the backup as very large backups can have issues
Two other differences are that you cannot do the system drive (C drive) using this type of backup and the backup selection list is different .. A windows policy would say D:\ but a Flashbackup-Windows policy will say \\.\D:
Hope this helps
