PROGRAM FOR SELECTIVE BACKUP MAC IMAP BACKUP

Program For Selective Backup Mac IMAP Backup

Also, the tool supports to backup IMAP Emails from various domains like Gmail, Yahoo, Hotmail, AOL, Outlook, iCloud on Mac OS.In information technology, a backup, or data backup is a copy of computer data taken and stored elsewhere so that it may be used to restore the original after a data loss event. Add an IMAP account and complete your backup in just a few steps. SuperDuper In a world where the slightest mistake can lead to data loss, SuperDuper is an essential app.The Mac IMAP backup tool efficiently backs up single and multiple IMAP mailboxes to a specified location. Disk Drill for recovering lost files. Smart Backup for greatest value. ChronoSync for ease of use.

A backup system contains at least one copy of all data considered worth saving. Backups provide a simple form of disaster recovery however not all backup systems are able to reconstitute a computer system or other complex configuration such as a computer cluster, active directory server, or database server. Backups can be used to recover data after its loss from data deletion or corruption, or to recover data from an earlier time.

Backup schemes may include dry runs that validate the reliability of the data being backed up. Additional techniques apply to enterprise client-server backup. The process can include methods for dealing with live data, including open files, as well as compression, encryption, and de-duplication. There are also different ways these devices can be arranged to provide geographic dispersion, data security, and portability.Data is selected, extracted, and manipulated for storage. There are different types of data storage devices used for copying backups of data that is already in secondary storage onto archive files. An information repository model may be used to provide structure to this storage.

An offsite copy protects against fire, theft of physical media (such as tapes or discs) and natural disasters like floods and earthquakes. 2 or more different media should be used to eliminate data loss due to similar reasons (for example, optical discs may tolerate being underwater while LTO tapes may not, and SSDs cannot fail due to head crashes or damaged spindle motors since they don't have any moving parts, unlike hard drives). It states that there should be at least 3 copies of the data, stored on 2 different types of storage media, and one copy should be kept offsite, in a remote location (this can include cloud storage). The scheme determines how and when each piece of removable storage is used for a backup operation and how long it is retained once it has backup data stored on it.The 3-2-1 rule can aid in the backup process. The repository could be as simple as a list of all backup media (DVDs, etc.) and the dates produced, or could include a computerized index, catalog, or relational database.The backup data needs to be stored, requiring a backup rotation scheme, which is a system of backing up data to computer media that limits the number of backups of different dates retained separately, by appropriate re-use of the data storage media by overwriting of backups no longer needed. 3 Manipulation of data and dataset optimizationA backup strategy requires an information repository, 'a secondary storage space for data' that aggregates backups of data 'sources'.

Typically a full backup of all files is once or at infrequent intervals, serving as the reference point for an incremental repository. Duplicate copies of unchanged data aren't copied. However, imaging is generally more useful as a way of deploying a standard configuration to many systems rather than as a tool for making ongoing backups of diverse systems.An incremental backup stores data changed since a reference point in time. Copying system images, this method is frequently used by computer technicians to record known good configurations. This method is the easiest to implement, but unlikely to achieve a high level of recoverability as it lacks automation.A repository using this backup method contains complete source data copies taken at one or more specific points in time.

This allows restoration of data to any point in time and is the most comprehensive and advanced data protection. When done to modify a single archive file, this speeds restores of recent versions of files.Continuous Data Protection (CDP) refers to a backup that instantly saves a copy of every change made to the data. Some backup systems can create a synthetic full backup from a series of incrementals, thus providing the equivalent of frequently doing a full backup. Restores begin with the last full backup and then apply the incrementals.

Other variations of incremental backup include multi-level incrementals and block-level incrementals that compare parts of files instead of just entire files.From left to right, a DVD disc in plastic cover, a USB flash drive and an external hard driveRegardless of the repository model that is used, the data has to be copied onto an archive file data storage medium. Changes in files may be detected through a more recent date/time of last modification file attribute, and/or changes in file size. Restoring an entire system requires starting from the most recent full backup and then applying just the last differential backup.A differential backup copies files that have been created or changed since the last full backup, regardless of whether any other differential backups have been made since, whereas an incremental backup copies files that have been created or changed since the most recent backup of any type (full or incremental). However, as time from the last full backup (and thus the accumulated changes in data) increases, so does the time to perform the differential backup. This means a maximum of two backups from the repository are used to restore the data. This can either be done using hard linksвЂ”as Apple Time Machine does, or using binary diffs.A differential backup saves only the data that has changed since the last full backup.

While tape media itself has a low cost per space, tape drives are typically dozens of times as expensive as hard disk drives and optical drives.Many tape formats have been proprietary or specific to certain markets like mainframes or a particular brand of personal computer. Tape is a sequential access medium, so the rate of continuously writing or reading data can be very fast. It was previously a less expensive option, but this is no longer the case for smaller amounts of data.

The Oracle StorageTek T10000 was discontinued in 2016. The other remaining viable 'super' format is the IBM 3592 (also referred to as the TS11xx series).
