Backup Strategies

Overview
A backup routine is a plan for backing up files on a regular basis. The main purpose of a backup program is to copy the files on a hard disk to a tape in case of a hard disk failure. Arcada Backup for Windows 95 also lets you recover deleted files, return to older file versions, create more space on your hard disk, and transfer files from one computer to another. 
Protect Against Hard Disk Failure
A hard disk can fail at any moment, rendering all data inaccessible. A "crash" can be caused by mechanical failure, software failure, an electrical surge, fire, water, or even dust and smoke particles. Partial hard disk failures are not uncommon. Sectors of a disk can lose magnetic retentiveness, resulting in corrupted or lost data. 
Statistics show that most hard disks represent an average of well over 3,000 hours of work. The data, and your investment of both time and effort, should be protected from loss. Arcada Backup for Windows 95 provides such protection. A properly backed up hard disk can be restored within minutes.

Protect Against Accidental Deletion
Almost everyone has looked for a file only to discover that it has been accidentally deleted. 
With a good backup routine, your data is protected from such mishaps. When files are backed up, they can be restored to your hard disk. Arcada Backup for Windows 95 has been designed so you can locate and restore files as you need them.

Access Older File Versions
You may need to save or go back to earlier versions of your files. For example, you may need to see an earlier version of a spreadsheet or word processing document.
With Arcada Backup for Windows 95, maintaining different versions of the same files can be a simple procedure. If backups are performed regularly, different versions of files will be available for quick and easy restoration.

Archive Files
It seems that there is never enough space on a hard disk. The urge to delete rarely used files is tempered by the possibility, however small, that these files may be needed again. 
Archiving can help. Archiving is the process of saving copies of selected files for future retrieval. Backing up data provides an automatic facility for archiving. After files are backed up onto tape, you can delete them from your hard disk. If they are ever needed again, they can be easily restored. 

Transfer Files
You may need to transfer a set of files to a new computer or to all the computers in your department. Or you may need to bring files home from work each day. Arcada Backup for Windows 95 lets you transfer files from one computer to another. You simply back up the desired files and then restore them to other computers.
You don't have to worry about fitting your files on diskettes or what to do with very large files, because you can fit most large files on a single tape cartridge. If you are transferring more files than will fit on one tape cartridge, Arcada Backup for Windows 95 will prompt you to insert another tape as needed.

Developing a Backup Strategy
Before you perform your first backup, you may want to develop a backup strategy. A strategy that ensures Arcada Backup for Windows 95 is set up in a way that matches your priorities.

Consider the following as you begin:
	What files must be backed up?
	How much time can you spend backing up?
	How often should files be backed up?
	What is the capacity of the tape drive available for backups?
	How important is it to automate backups?
	Will you be working alone or does your routine depend on others in your organization?
	How important or valuable is your data?
Once you've made these decisions, you can get started. These issues are addressed in this chapter.
File Selection
There are as many approaches as there are Arcada Backup for Windows 95 users. Here are some considerations in backing up data files and program files.
	Data files
A common practice is to back up data files daily or weekly. However, if losing one day's work is more than you can afford, consider backing up more often.
	Program files

You may want to back up your program files during each All Selected Files backup, every few months, or when you add or reconfigure a software package. 
TIP: Backing up program files saves you the time and trouble of reinstalling and reconfiguring them from the original program diskettes if a problem develops.
Whenever you perform a backup, you can back up one file, one directory, or a set of files or directories on one drive or multiple drives. You can make your file selections each time, or save your selections and reuse them.

Flexibility
You can back up all your drives, including network drives, at one time. Or, you can base your backup on how frequently a set of files change. Then you can make monthly, quarterly, or semiannual backups of files that seldom change (program files), and daily or weekly backups of files that change frequently (data files).

Organization
Further, you may want to make separate backups of different types of data files. It is easiest to do this if you keep related files grouped together in their own directories or give them the same file extension. For example, it is easy to make separate backups of spreadsheet, graphics, and word processing files if each type is contained in its own directory or has a unique file extension. 
However, if you work on projects that require spreadsheet, graphics, and word processing files, it is easiest to back up all the project-related files if you keep them in one directory. If you keep your files in separate directories, you can still create a backup set of all the project files by selecting them from various directories. The backup set you create can also be used to archive files at the project's completion.

Backup Types
Arcada Backup for Windows 95 offers three backup types:
	All Selected Files backup
	New and Changed Files backup (Differential)
	New and Changed Files backup (Incremental)
Use the All Selected Files and either the incremental or differential backup types on a regular basis to safeguard your data.

All Selected Files backup
An All Selected Files backup creates a backup set containing all the files that you select. It can include all the files on your hard disk (a total backup) or can include any combination of drives, directories, and files you designate. 
You can back up your data by making only All Selected Files backups, but this is inefficient. Instead, Arcada Backup for Windows 95 lets you save time by letting you perform partial backups that include only files that have changed. 
An All Selected Files backup copies all selected files. Incremental and differential backups look at that same set of files and copy only the files that are new or have been changed since the last full or incremental backup.
NOTE: If you only select individual files manually, new files will not be backed up during an incremental or differential backup. If you want new files to be included, make sure the drive or directory where the files are located is selected.

Differential Backup
A differential backup backs up all the selected files that have changed since the last All Selected Files backup. Therefore, a differential backup may take a little longer to complete than an incremental backup. On the other hand, you have to keep only the last full and the latest differential backup sets to restore files successfully, so this choice may result in less tape space needed for the entire backup set.

Incremental Backup
An incremental backup backs up all selected files that have changed since the last full or incremental backup. Because an incremental backup backs up only files that have changed, it is quick, and you're fully protected against data loss. 
For example, you might do a All Selected Files backup on Friday and incremental backups each business day. You will need to keep all the backup sets made from Friday to Thursday. If you do the All Selected Files backup on Friday and have to restore on Wednesday, you'll need the backup sets made on Friday, Monday, and Tuesday. 

Backup Cycle
For a backup system to remain effective over time, backups must be implemented in regularly maintained cycles. A backup cycle begins when you perform an All Selected Files backup of a set of files and includes all the incremental backups you subsequently perform. A new backup cycle begins when you perform the next All Selected Files backup of the same set of files. The backup cycle for a set of files may last a day, a week, a month or longer if you prefer.
Backup cycles for different groups of files may be of different durations, depending on the types of files and how you use them. Your backup software keeps track of all the backups you perform as part of a backup cycle, to help you easily restore any files you have backed up.

To set up a weekly backup cycle with an All Selected Files backup on Friday and incremental backups on Monday through Thursday, use the following procedure.
To create a weekly backup cycle:
1	Label your tape. If your backup requires more than one tape, label and number each tape so you can recognize them easily.
2	Start your cycle on Friday. Insert your first tape in the tape drive and perform an All Selected Files backup. 
3	On Monday, reinsert the tape you used for the All Selected Files backup and perform an incremental backup. The incremental backup automatically appends to the All Selected Files backup. The tape now contains all files backed up with the All Selected Files backup plus all files that were created or changed since the All Selected Files backup.
4	On Tuesday through Thursday, perform incremental backups. Each subsequent incremental backup appends to the previous backup. If you need more than one tape, you will be prompted to change tapes. After your Thursday backup, you will have a complete rotation set.
5	On Friday, begin the cycle with a second set of tapes.
Create two backup tape sets and alternate between the sets so that the most recent set is maintained while overwriting the previous tape set. Be sure to label your tapes so that you maintain two separate sets. If you are using your backup software for the first time, back up all of your files immediately. After your files are safely backed up, you can use the Schedule Backup Job dialog box object to establish a regular backup cycle.

Ensuring a Reliable Backup
A reliable backup depends, in large part, on the regularity of your backup routine. You must also select the right files and options, and properly care for, label, and store your backup media. If you are backing up to removable media, use only high-quality tapes that are compatible with your drive.
Arcada Backup for Windows 95 offers two additional tools to help ensure the reliability of your backup sets: 
	Verify Data
	Compare

Verify Data
If you back up with the Verify Data backup option on, Arcada Backup for Windows 95 will verify the data by reading it back from the backup medium after writing it and comparing it to data on the disk. Because Verify Data slows down performance, you may choose to turn Verify Data off. However, it is strongly recommended that you use Verify Data to help ensure the reliability of your backups.

Compare
After you have created a backup set, you can go to the Compare window and verify that the information contained on the backup tape is identical to the data on the hard disk and that it can be restored. Compare is a separate function designed to provide maximum data security. It checks the data in the backup set against the source data on the hard disk. 
Compare:
	Reads the data on your backup medium exactly as if it were going to restore the data to the hard disk.
	Compares this data to the data found on the hard disk.
	Verifies that they are identical or displays a message when files do not match. 

NOTE: It is strongly recommended that you perform compares after your first few backups and after changing your system's configuration. This will confirm Arcada Backup for Windows 95 is running properly on your computer.
TIP: Performing a compare at any time in the future lets you see how the files in the backup set differ from the files currently on the hard disk.

Backup Jobs
Before you begin a backup, files, settings, and options must be selected. These selections can be stored in backup jobs and reused. Backup jobs let you eliminate as many of the repetitive procedures as possible. As a result, they speed up and simplify the backup process.
A backup job includes all the selections made at the time it is saved, including: 
	Drives to back up 
	Automatic file selections 
	Backup type
	Options selected
A backup job is created by selecting program settings and options and making file selections, then saving those choices as a new backup job.
An unlimited number of backup jobs can be created and saved with different descriptive names, so backups can be performed with a minimum of time and effort. Backup jobs can be distributed to other users to implement standardized backup procedures.

Schedule Backup Job Dialog Box
Arcada Backup for Windows 95 includes a Schedule Backup Job dialog box which lets you schedule automatic backups. With the Schedule Backup Job dialog box, you can select a backup job to be used, the frequency of the backup, and a starting date and time. Using the Schedule Backup Job dialog box, you can plan and automate all your backups for the foreseeable future in a few minutes. All you have to do is to remember to leave your computer on with Windows 95 running and a tape in your drive, if you won't be at your computer, or respond to the prompt to insert a tape when the time comes.

If you are working in another application at the time a backup is scheduled, Arcada Backup for Windows 95 will run safely in the background, provided the other application does not need access to the floppy disk or tape drives.
