LTO 7 Tape compression
Hi All,
Need your adivse, we have brought LTO 7 tape library and implemented.
however i need your advise on compression mode? i have gone thru some articles, dont understand what exactly tape compression means, i have noticed, by default my tape drives show " compression ON" (DELL power vault TL4000). is it compression backup is recommended? what is pro and cons?
Thanks in advance.
Have a look at the Wikipedia link in Tape_Archived's post.
You will see that the Native/raw capacity of LTO5 is 1.5TB and for LTO7 6TB.
Always use raw capacity for capacity planning, as you don't know if all data to be backed up is compressible.
