I have Dell R630 5TR Raid-5, 64G RAM housing Ubuntu-16.4. it is integrated with my SIP Soft switch. We use the Datto backup service that allows us to install a Datto Agent on the Ubuntu servers and the Datto agent software performs hourly backups. Three other U16.4 servers back up just fine. According to Datto support, they have seen this before where during the FTP transfer from the Ubuntu machine to the Datto server, data becomes fragmented. They claim the fsck needs to be run on the partition. I have attempted to do just that, however, partitions need to be dismounted and few other preemptive steps need to be taken. We are a small business, Mitel phone system distributor hosting our own VOIP platform I don't have any Linux-trained techs available so I would rather pay a knowledgeable Ubuntu/Linux familiar tech. Datto will not help, as far as they are concerned the backup server is running just fine, and it is.
Also, I have other windows server projects on the back burner waiting to be done. If I can find a reliable freelancer I can work with then I can keep him or her busy. I have no trouble paying top rates but I do expect professional, reliable support. All my servers in the office and data center can be managed remotely I am flexible with time and scheduling. Any out of service situations will be handled by my service agreements with Softswitch. basically, I need a tech that will handle projects outside of my support plans.
let's have a video conference call and discuss details. Let me know your availability I am now in the process of interviewing bids and contractors/freelancers who have responded to my request.
