[louacif]

hello,

can any one tell me how i can backup my mail server. the problem is :

i have done backup of  some files which contains mail.
when i restore, the existing file is replaced but i want keep the current data and restore the old data or data lost only in this file.

NB : server linux 5.3, netbackup 6.5

The restoration part seems to be ok.  But make sure replication of the mail file (which is restored) is disable from mail application for that mail file before you restore the backup. 

Also, as a best practice always restore in different path.

i think that i have not explain the problem correctly.

i want to restore the file but i dont want lost the current data in the same current file

Will need to "restore to different location" when you're doing the restore, so it doesn't overwrite the existing file.

but what about the current data, i think that i will lost it

When you restore the data to new location your existing mail file will remain in old location, it will not be lost.

You have to merge those files by hand, netbackup can't do it for you.
