I have 3 servers with 4 disks configured with data dedupe. All are VMs in VMware ESX-i 5.5. All are server 2012R2 64 bit. I use both EMC legato and Symantec Backup Exec to backup the 4 disks. When using EMC the incrementals are ignored every 4th week/28th
day and it runs a full backup instead. I used Windows backup to confirm this was only an EMC issue. I am unable to find out what is scheduled every 28th day on disks configured with data dedupe. All my configs are out of the box default. I have not added anything.
EMC engineers have been unable to find the fault in 4 months. I have gone through every scheduled event on the server, there is nothing that runs every 4 weeks. all other servers act normally. Even disks not configured with data dedupe on the same servers
run incremental backups properly. This is isolated to EMC and data dedupe disks. I also get the "quota limit exceeded" emails "User ENG\Administrator has reached the quota limit
for quota" every 28th day on the same day the inc. backups are ignored and fulls run. I cannot find out what invokes the emails to be sent. There must be something that does a whole refresh of the data on the disk and resets some element of the file and
folder metadata that is not used by either Backup Exec or server 2012 R2 windows server backup. Any suggestions what runs on data dedupe configured disks by default every 28 days?
