This section contains important details you should be aware of when using single Zip compression with cloud storage, FTP/SFTP or SyncBack Touch and you are using Fast Backup. |
Audience
Single zip compression is where you have configured SyncBack to put all your backup files into a single compressed file. The alternative is multi-zip where each backup file goes into it's own compressed file. Here we are going to talk about single zip compression only as multi-zip compression does not act the same way.
Single Zip with Cloud storage, FTP/SFTP and Touch
When you are backing up all your files to a single Zip file file in remote storage such as the cloud, FTP/SFTP and Touch, then the backup Zip file is always deleted and replaced with a new backup. This means it will always make a full backup of all your files. It will not update the backup files. It will simply replace the backup with a new one. You can of course use variables in your single Zip filename so that you have multiple backups, e.g. a new backup for every day of the week. The point is, SyncBackPro will not download the remote backup Zip file, update it and then upload it to replace the existing one. It will instead create a new Zip file and then upload it, which replaces any existing backup Zip file.
Fast Backup and Single Zip with Cloud storage, FTP/SFTP and Touch
You can change this by using Fast Backup. With Fast Backup, SyncBack compares the current state of your local files to the previous state when the profile was last run. This means it doesn't need to scan the backup destination (the Zip backup file) to see what has changed. It also means it is not going to backup everything again. Instead, it is only going to put into the new backup Zip file those files that have changed since the last run. In other words, it is going to make an incremental backup. You can change this in the Fast Backup settings to make it a differential backup instead.
The important point to remember is that the backup Zip file is an incremental or differential backup and not a full backup. This new backup Zip file will then replace any existing remote backup Zip file. Unless you are using variables in your backup destination then this is very probably not going to be what you want.
For example, you are making a backup to FTP, are using Fast Backup, and have configured your profile to backup all files to a single Zip file using the file name MyBackup.zip:
•The first time you run the profile it will make a full backup. MyBackup.zip will contain a backup of all your files.
•The second time you run the profile it will only put new and changed files into MyBackup.zip, which will then replace your existing backup.
•You've now lost the backup of your unchanged files.
We recommend you:
•Enable the auto-incrementing variable and configure it to how many backups you want to keep (one backup will be full and the others will be incremental or differential)
•Change your backup file name to use the auto-incrementing variable, e.g. MyBackup_%AUTOINC%.zip
•Configure your Fast Backup to force a rescan when %AUTOINC% equals 1 (or whatever you set your minimum value to be for the auto-incrementing variable)
•Optionally, configure your Fast Backup to use Differential backups. Differential backups will use more space but are quicker to restore.
If you do the above, you will have one full backup and several incremental or differential backups (how many depends on the maximum value you used for the auto-incrementing variable).
