Advanced (Backup Configuration)
Configuration
To access the Advanced options, click the Advanced tab. Refer to the image below.
- Delete Files From Server - when checked, Syncrify will delete file from the server if the corresponding file is deleted on the client. When this is not checked, a copy will remain on the server.
- Send Notification Email - Check this box if you want Syncrify client to generate an email when a backup is completed. The box next to the check box is used to specify the recipient(s) of the email report. When this box is left blank, the login ID is used as the recipient address. Use a comma to separate multiple addresses.
This email is only sent when a scheduled backup is run. Email is not generated when a user manually runs a backup.
- Compress Data - when checked, smart compression is used before sending the data over the network. During the backup if no significant size reduction is gained by compressing a file, data gets sent as-is. Consider a scenario where you have large files containing a relational database, which can be significantly reduced in size by using compression. On the other hand, files like MP3, JPG do not reduce in size when compression is applied. In such cases, the compression step is eliminated saving CPU cycles on both client and server.
- Enable Versioning - when checked, multiple versions of every file are stored on the server. The number of older versions maintained on the server is defined by the administrator who is managing Syncrify server. A version is only created if a user modifies a file.

Client to Server
This is the default behavior. When a backup is run, newer files on the client machine are backed up to the server machine. No files are copied from the server to the client.
If Delete Files is checked, files deleted on the client will be deleted from the server as well, unless Delete Retention has a value greater than 0.
Two-way Sync
Newer files are copied in both directions - meaning if a new version of a file exist on the server, it will get copied (or restored) to the client. Similarly, a new file on the client will get copied (backed up) to the server.
The Delete Retention option has no affect when Two-way sync is enabled.
This option is not available in the Personal Edition of Syncrify.
Server to Client
Files on the server are copied to the client if they are different. This is similar to running a restore operation with one difference: If Delete Files is checked, local files on the client will be deleted if they do not exist on the server.
This option is not available in the Personal Edition of Syncrify.
To select Backup Types, click the 
button at the lower right-hand corner.
Additional Configuration
Backup Type - Provides finer control over how files are copied to the destination server.
Synchronize Timezone - Files on the server will use the same timezone that is being used on the client. If disabled, files on the server are stored using GMT timezone.
Send email only on error - Once a backup job is complete, Syncrify client can send email to the user containing a list of files that were modified. This email is sent only when you run backup from console or through scheduler. Email is not sent when running backups manually.
Use folder cache - Syncrify creates a local cache file containing this list for comparison. This cached data is stored in a sub-folder called FolderCache off of the Data Folder.
Delete after backup - Syncrify will delete files on the client after they have been successfully backed up. This option is only valid when backup direction is Client-to-Server.
Delta Backup
This is the default and uses the rsync algorithm to determine the difference between files and sends non-matching blocks over the network.
Simple Copy
Using this option disables rsync and will force the client to send the entire file, skipping the block matching process. You should only use this option if both Syncrify client and server are on a very fast network, such as same machine or LAN.
Smart Backup
- Backup direction is either Two-way sync or Server to client
- Versioning is enabled.
In this case Syncrify will switch between Delta and Simple backup depending upon the file size and network. For example, if you have a 1 GB file on the server and the file size on the client is 10 MB, it is much fast to transfer the entire 10 MB across the wire rather than matching blocks on a 1 GB file.
