VeeamON 2024 - Use Code "COMMUNITY10" for 10% Off!
Great detail, and very helpful. Thank you.
Thanks for this - it goes into the script immediately.
The pointer based synthetic full will be reconstituted as a full backup unless you can clone the file system block for block.Has anyone tried the BackupCopyMirrorAll registry key? This supposedly will work to copy old backup chains from one repo to another.
This is a good and very timely review of basic yet overlooked security best practices. I posted in LinkedIn. Thanks for this, especially after the latest high-profile hack at Colonial Pipeline.
I especially liked the illustrations. They drive home the abstraction of the 3-2-1-1 rule statement (kind of like the Three Laws of Robotics...oh boy, nerd alert). Thanks for this. I’ve shared it and reposted already and have it bookmarked for future conversations.
Correct...and an edit is needed! Use Performance Policy (as opposed to Data Locality Policy), not Performance Data Locality Policy. 🤦♂️
A few more points:Immediate copy is the only choice for Enterprise Application Backups. This has a bearing on managing how the BCJ impacts resource consumption and scheduling. RMAN script: Every backup job process includes the following three phases. Ask customer to separate the catalog resync from the backup/crosscheck steps. The three way connection needed among the database server, Veeam backup server/repo and the RMAN Catalog Database can prolong the duration of the RMAN plug-in backup job. Backup Crosscheck Catalog resync RMAN – dig into the details of how backup jobs are scripted, since this will impact your concurrent task slot usage and duration of each phase. How many backup files per set? How many channels per database backup? How many channels per redo log backup? Does the backup method include Full (level 0) and incrementals (level 1-9), or cumulative incrementals? Full backups daily will consume more repository space, prolong the backup job and prolong the backup co
Yup, two more points (this is helping me put my list together...):Immutability will not be applied to RMAN backups, if sent to a Linux repository set for immutability. Fast Cloning will not apply to RMAN backup files.
Two more points (this might go on all day...)Dedicate the repository to Oracle RMAN in large environments. Don’t mix in VM workloads. This is both a resource issue and a configuration issue. See the point below. If targeting a SOBR, use the Performance Data Locality policy, so load balancing is based on available compute resources (cores). Note that this means that any Oracle database and redo log backups will likely be spread across extents. This setting works for plug-in backups since there is no Full and Incremental backup from Veeam’s perspective.
You’re welcome. I should have edited item 2, since those numbers related to a ratio of cores on a physical server. It would be better put as “Reduce tasks on the BCJ target repo servers to 10-20% of the tasks allocated to the RMAN plugin tasks.”Hope that helps.
I was asking this same question recently and did not get any “real-world” responses. I have a customer that is deploying this at scale and I’ve been assembling some best practices. The biggest issues were resolved with v11, and the metadata improvements. One task = 5 channels, so plan repository resources accordingly. If doing a backup copy job, make sure you keep that in mind as well - limit the tasks on the target repo so it doesn’t suck up all the task slots on the source and hang up the RMAN jobs (especially the archived redo log jobs). I recommend increasing the registry settings for max user ports to 64K and shortening the TCP timed wait delay to 30 seconds. Summary of the big points.:Recommendations for infrastructure optimization:Set a backup window for backup copy jobs? No, no need. Reduce tasks on the BCJ target repositories, set to 20 or 30 per extent server BCJ can be set at repo level if there are two Oracle repos with different retention (e.g. for Prod and Non-Prod), or a
Very helpful page to send all my customers to when they upgrade, which should be very soon. CDP and Hardened Linux Repo are driving my customers to upgrade, and perhaps to purchase. Thank you, Rick!
Not yet, but I have a few customers VERY interested and will be testing soon with them. I will update here.
