Why would HANA db disconnect take place during backup copy procedure?

300 Views

We run on ECC 6.0 EHP 7 Suite on premise on HANA 1.00.122.12 VM SLES. We also replicate to a backup DB for DR purposes. During off hours we backup the DB to disk then copy to another storage location for final backup. During the copy (CP command) procedure there is frequent escalation of both CPU & Memory. Unfortunately, nearly daily at the same time, there is also a momentary disconnect to the database. Any jobs running during that time will fail as a result.The indexserver trace file often reports a timeout and broken connection, but not always. SM21 shows job failures, but not the same job daily. This started happening just over a month ago (APR 3), but we cannot relate it to any change that took place in our system environment.We have checked VM, Network, System, Backup, HANA, and Storage statistics and have run traces. We have opened incident with SAP, but have no answers after all of this.Anyone experiencing the same or similar?
