Fastest backup destination will be either Local storage (provided that it's on a separate device), or remote SSH destination (provided that the bandwidth is very high and fast).
For best performance, it is also recommended to exclude files/folders, and disable backup for suspended accounts.
JetBackup is a backup management software that allows you to choose your own backup destination storage. It does not however provide or come with its own storage space. Click on Destinations Overview for a list of all supported desinations.
While JetBackup supports almost any characters for filenames (UTF-8), there are special characters/symbols that are generally best avoided as there are specific limitations across various filesystems and storage destinations which can cause unintended issues with your backups.
This list is not exhaustive and is meant to help determine and avoid errors regarding filenames and your backups.
| # pound | % percent | & ampersand | { left curly bracket |
|---|---|---|---|
| } right curly bracket | \ back slash | < left angle bracket | > right angle bracket |
| * asterisk | ? question mark | / forward slash | blank spaces |
| $ dollar sign | ! exclamation point | ' single quotes | " double quotes |
| : colon | @ at sign | + plus sign | ` backtick |
| | pipe | = equal sign |
Prior to adding a destination to JetBackup, we advise securing the backup directory, so that only the allowed users can access that folder.
mkdir [-p] /mnt/backup_vol/jetbackup
Then we advise securing that destination so only one user can access it's content (except root)
useradd <jetbackup>
chown jetbackup:jetbackup /mnt/backup_vol/jetbackup
chmod 700 /mnt/backup_vol/jetbackup
Right now, only users root and jetbackup can access this directory.
Please search online, how to secure a backup folder for your particular file system (EXT, NTFS, FAT, etc..) on your system (Windows, Linux, macOS, BSD, etc..)
For more information, and a good start point please visit File System Permissions
Now, when adding that destination in JetBackup GUI, the specified Backup Directory should be the directory you have just created and secured: ie /mnt/backup_vol/jetbackup
NOTE: JetBackup utilizes rsync when backing up to an NFS destination. Ensure your version of NFS has full support for rsync.
