Hello guys: I'm planning a Bacula deployment on AWS in the following weeks. I have some doubts about disk performance for Disk based backups.
Based on the idea that Bacula writes data on big files (i.e. 100 GB each volume), what technical considerations should I have for the underlying storage device? These are some of my questions I have around it: - Does it matter a lot choosing XFS instead of ext4 as filesystem? - How can I know the amount of IOPS needed for my local disk? - What does Bacula need most: high IOPS or throughput (MB/s)? - Based on the previous question, should I choose SSD over HDD disks? - Is it worth using RAID1 or RAID10 for improving performance? I was planning to use HDD disks which offers high throughput (500 MB/s) and up to 500 IOPS per disk (these are "st1" EBS volumes). By the way, I pretend to use an external DB (Amazon RDS) for my Catalog, so my Storage daemon wouldn't share the same underlying storage. I hope someone can share some ideas about disk performance. I didn't find enough info about this topic on Internet.
