Restoration Size
Hello Experts,
I tried restoring 5 kb file from tape but could see it showed me 167410176 KB Current kilobytes read.
What is this size since the file is 5 kb only?
Thanks,
I think that figure is the amount of data that had to be read (or skipped through) to locate the file that you wanted. If you had chosen to restore a file which appears earlier in the 'backup image' then the figure displayed would be lower. (I think).
Hey Harygan
Take a look at this tech note , I think you will find interesting
How "Maximum Fragment Size" for a Storage Unit affects backups and restores
http://www.symantec.com/docs/TECH15692
- Fragments are written after completing a file backup. So, for a 600GB backup image, fragment filemark will be written when it gets to 300GB after current file backup has completed. When you want to restore a particular file, NBU will know in which fragment the file was written, position to the fragment number and only read that 300GB fragment to find the file. Restores are much faster with smaller fragments, but will slow down backups when the fragments are too small. Backup is paused when the fragment is written. There are other posts on this forum that deals with recommended fragment size.
