one of my exchange server D drive got filled , it suddenly showed o bytes out of 90gb,
we ran tree size software to check what caused it to fill it up. we could not see except pagefile.sys.
we tried to remove some.pst files from D drive to C drive got some space but it got filled right away.
we also tried to involve storage team to increase the disk space by 10 gb got filled righta way.
we could see on D drive there were only 3gb files , we checked hidden files and extension, nothing found
finally we saw one backup process was running which was filling THE DRIVE, and no files found still, so what was going n background?
we do back from vision third party
my question is how a backup process could fill the drive? when there were no transaction logs on that drive
