Performing an incremental, selective, or incremental-by-date backup (UNIX and Linux)
Your administrator might have set up schedules to automatically back up files on your workstation. The following sections discuss how to back up files without using a schedule.
There are two types of incremental backup: full incremental and partial incremental.
- Full and partial incremental backup
An incremental backup backs up only new and changed files. The type of incremental backup depends on what objects you select to be backed up. - Incremental-by-date backup
For a file system to be eligible for incremental-by-date backups, you must have performed at least one full incremental backup of that file system. Running an incremental backup of only a directory branch or individual file will not make the file system eligible for incremental-by-date backups. - Comparing incremental-by-date, journal-based, and NetApp snapshot difference to full incremental and partial incremental backups
Incremental-by-date, journal-based, and NetApp snapshot difference are alternatives to full incremental and partial incremental back methods. - Snapshot differential backup with an HTTPS connection
You can use a secure HTTPS connection for the backup-archive client to communicate with a NetApp filer during a snapshot differential backup. - Selective backup
Use a selective backup when you want to back up specific files or directories regardless of whether a current copy of those files exists on the server. - Solaris global zone and non-global zones backups
For Solaris zones, perform incremental and selective backups of file systems within the zone where these file systems were created. - Saving access permissions
When you back up your files, the backup-archive client also saves standard UNIX access permissions assigned to the files. - Setting a virtual mount point
If you are an authorized user and you want to back up files beginning with a specific directory within a file system, you can define that directory as a virtual mount point. - Backing up data using the Java GUI
You can back up specific files, entire directories, or entire file systems from the directory tree. - Backing up data using the command line
You can use the incremental or selective commands to perform backups. - Deleting backup data
If your administrator has given you authority, you can delete individual backup copies from the IBM Spectrum Protect server without deleting the entire file space. To determine if you have this authority, select File > Connection Information from the backup-archive client GUI or web client main menu. Your authority status is provided in the Delete Backup Files field. - Deleting file spaces
If your IBM Spectrum Protect administrator gives you authority, you can delete entire file spaces from the server. When you delete a file space, you delete all the files and images, both backup versions and archive copies, that are contained within the file space. For example, if you delete the /tmp file space, you are deleting every backup for every file in that file system and every file you archived from that file system. Carefully consider whether you want to delete a file space.
