Just like any other type of server, reevert needs enough resources to perform as optimized as possible:
reevert will be using CPU mostly to compress data while uploading to the cloud. If you will be running several parallel uploads, the more CPU cores your appliance has, the faster it will perform compression.
If using a virtual appliance, we recommend using a storage solution that utilizes at least 7200rpm disk drives. Depending on your data situation, reevert can be performing a lot of I/O operations. The faster your storage is, the happier your appliance will be.
About 30% of your appliance's memory will be dedicated to file system caching and the rest will be used as on demand cache mostly for file server services or when performing cloud uploads. The more cloud uploads you are planning to perform, the more memory allocation is recommended. We usually recommend a minimum of 8GB but a 16GB allocation will perform much better.
Your appliance will be compiling and emailing a summary report every Monday. Pay attention to this report since it has valuable information such as performance stats.
Multiple Appliances / Hardware Appliances
If you require a large number of backup workloads, multiple locations or simply don't have enough local storage, consider deploying multiple appliances or check out available hardware appliances.
Allocating Storage Space
Allocating space is all about the frequency in which your data will change on daily basis and how many local snapshots you are planning to keep on-site. Keep these points in mind:
Review your snapshot settings. Make sure they comply with your firm's requirements and the amount of local storage you have access to.
It is all about the amount of changes
Remember: the more changes your data has, the more local storage may be needed. Your reevert appliance is very efficient when it comes to using storage. It takes block level snapshots and applies file system compression. However, if your data is changing a lot on a daily basis, take that into considerations.
We have an Online Calculator that can be helpful when it comes to estimating how much storage you may need.
General Rule of Thumb
We recommend to allocate twice as much as your total data size for your backups. If planning to backup more than 3TB of data, we highly recommend a hardware appliance.
Keep in mind, reevert comes with its own storage space monitoring system and will email you if the usage on any storage pools that reach the 80% threshold. You can easily expand your storage pools by adding new virtual disks if you are using a virtual appliance. You can also delete older snapshots or adjust your snapshot settings to free up space.
Cloud Upload Considerations
One of the most important aspects of using reevert is utilizing its cloud upload capabilities to perform off-site data replication. There are some important points that you need to consider while setting up cloud backups for your appliance:
Perform Environment Assessment
Make sure to fully assess the environment to know how much data will be backed up and what the available internet speeds are. This is very important to balance the upload jobs and allocate enough local storage space.
Upload Speed Throttling
Make sure to do a speed test and throttle the upload speeds. We recommend allocating a maximum of 30%-50% of your upload speeds during business hours to reevert. You can lift the limit after business hours to help the uploads finish as fast as possible.
Balancing Data and Upload Speeds
Depending on how much data you are planning to upload and how fast your upload speed is, you may not be able to perform very frequent uploads (e.g. performing daily uploads) and you may limit some of your upload schedules to once a month only. This is a very important factor. Please take this point into consideration to avoid situations such as piling up upload jobs; these will have a hard time being completed.
Archive Historical Data
The best way would be to archive any historical data that does not change and simply perform a one-time upload for that. This will prevent repeated uploads for something that does not really change.
Cloud Storage Costs
Cloud storage is not included with your reevert's subscription and is something that you will be purchasing yourself. Storage costs can vary depending on how much data you are planning to upload or the type of cloud storage you are planning to use. We have a Storage Matrix page that may be helpful when deciding on which storage provider to pick.
Utilizing Image Backups
Image backups should be one of the core components of your backup policies. When utilizing reevert's image backup system:
reevert offers full and differential type image backups. Utilizing differential image backup types will help reduce the storage usage and will substantially speed up the backup process since only changed portion of a system will be backed up.
Large Storage Considerations
If you have servers that utilize large drives full of data, we highly recommend backing those up using backup sets and only backup the OS drive using image backups. This creates more frequent backups (every hour) and can potentially save a lot of storage space on your appliance.
We recommend using Monthly Full + Daily Differential backups. This will ensure you can restore your systems back to a most resent status with the most efficiency when it comes to utilizing resources including storage.
Adjust Backup Retentions
Make sure to adjust your image backup retentions to meet your needs yet provide the most efficient methods to utilize your local storage.
Image Backup Cloud Uploads
In most cases your upload speeds may not be fast enough to push image backups on daily basis. However, you can opt-in for once a month (monthly) cloud uploads that will push a number of full and differential image backups to the cloud. These uploads start at the beginning of each month and they gradually run until they are done.
There are several email notifications in place that will notify you if any of the image backup jobs fail. There is also a daily stats report that will show you image backup stats performed within the past 24 hours.
Utilizing Backup Sets
Backup Sets is a great tool to backup files and folders from any computer on your network. It supports Windows, Mac, Linux, and Unix. Keep in mind:
They Run Every Hour
Backups automatically run every hour. This means the data on the appliance will be in constant sync with the source.
Use VSS for Windows
Windows systems will be backed up via volume shadow system (VSS) to be able to backup locked files and folders. Mac, Linux and Unix systems will be backed up using rsync over SSH.
AppDate and ApplicationData
When backing up Windows machines (specifically the Users folder), make sure to NOT include entire AppData and ApplicationData folders in your backup sets. These two folders include temporary and system files that change frequently, which will drastically increase your backup size, without adding any real value. If there are specific files in those folders that you need to backup, individually include those.

Maintaining Your Appliance
Your reevert appliance is designed to be self-sustainable, but just like any other computer system, it may need your attention every now and then.
Reevert Agent and Anti-Virus Programs
One of the issues that you may encounter after deploying your appliance is your Anti-Virus program falsely alerting you about a suspicious file in your network. Reevert has an agent that gets stored as \Windows\winexesvc.exe. Please make sure to add this file to your Anti-Virus program's exclusion list.
System Tasks and Logs
This is a central location where you can review current, future and past tasks and access logs when trying to troubleshoot issues. In addition to these logs, backup processes create extra logs under source computer's \Windows\Logs folder. These can be very helpful when trying to troubleshoot backup issues or errors.
Your appliance will generate email alerts when important events happen. These alerts include storage space monitoring, memory usage monitoring, backup issues and many more. Pay attention to these emails and be proactive when acting upon them.
If you receive this alert after running your appliance for a very long period of time (90+ days uptimes), restarting file server services from the dashboard may be able to free up some of the used memory.
