Backups are performed according to policies determined by the specifications of the computers. The policy defines various levels of backup (full, different types of incremental), and saving “generations” (versions) of information snapshots at points in time.
This is done as follows:
VEEAM Virtual Servers Physical servers and NAS
| Backup copy | Backup type | Frequency | Retention | Backup Time |
|---|---|---|---|---|
| Copy (1) on-premise for Vmware & physical servers | Full | Once on the first backup | 3 Months | |
| Full synthetic | Weekly Every 4-th weekly | 4 weeks 3 Months | Night Night |
|
| Incremental | Every day | 30 days | Night |
|
| Copy (2) offsite for Vmware & Physical servers 14 days immutable (cannot be erased) | Incremental | Every day | 30 days | Night |
| Full synthetic | Weekly Every 4-th week | 4 weeks 3 months | Night Night |
|
| Copy (3) tapes offsite for Vmware & physical servers | Incremental Full Full | Every day Weekly Annually | 4 weeks 4 weeks 7 years | Night Weekend Year start |
| Copy (1) on-premise for NAS | Full Incremental | Once on first backup Every day | 3 months 90 days | Night |
| Copy (2) offsite for NAS 14 days immutable (cannot be erased) | Full Incremental | Once on first backup Every day | 3 months 90 days | Night |
| Copy (3) tapes offsite for NAS | Full | Weekly Annually | 4 weeks 7 years | Weekend Year start |
Synthetic full backup is built by the backup system from Full backup and the incrementals
The offsite copies are stored outside the Technion
