This may seem to be an ameture question. We have a Small Business Server 2003. Currently two backups are scheduled as full backups on a daily basis. One is done on tape using BackupExec 11d and the other is on an external HD. Additionally, Small Business Server 2003 also does weekly backups on the same external HD.
Recently, due to the increasing size of user data, the external HD can no longer hold two sets of backups and we started looking into using incremental or differential backup strategies.
My concern is, with both BackupExec and NTBackup running full backups, will incremental or differential backups work? The tape can hold full backups daily without problem so we'd like to keep it this way. We wanted to schedule NTBackup using full+incremental. For instance, on Monday, NTBackup runs a full backup at 8:00PM and BackupExec runs a full backup at 11:00PM. On the following day, if we schedule an incremental backup, which full backup would it recoginze? BackupExec or NTBackup? Since both will reset the the archive bits, I am afraid that it may cause confusion when it comes to restore.
Currently, no plans to purchase additional hardware.
Thanks in advance for any comments.
