Is Backup Tape Dead?

I just had someone contact me and ask my opinion if I thought backup tape is dead. Maybe 6 years ago I would have enthusiastically said "Yes!", and did so many times. However, after spending the last 6 years dedicated to cloud backup and immersed in the backup industry, my views have evolved on tape. Instead of asking "Is tape dead?", the proper question is "Has the use of tape changed?". While tape is far from dead…

Asigra Reporting “Cannot Allocate Memory” During Seed Import

We have DS-Systems running on Linux and we connect the Windows Seed backups to a Windows 7/8.1 machine and then use CIFS to mount the Windows share to Linux. The command we use on Linux to mount the Windows share is: mount -t cifs //<ipaddress of windows machine>/<sharename> -o username=administrator,password=xxxxxx /mnt/seed We were importing some large backup sets with millions of files and started noticing "cannot allocate memory" errors during the seed import process.

Asigra Slow Seed Import

We recently discovered that Asigra DS-System v13.0.0.5 seems to have a serious problem with importing seed backups. This problem exposed itself as we attempted to import 5.5TB of seed data.

On the same infrastructure, the same server seed backup imported into a v12.2.1 DS-System in less than…

Zerto Backup Overview

Zerto is primarily a disaster recovery solution that relies on a relatively short-term journal that retains data for a maximum of 5 days (at great expense in disk storage). Many Zerto installations only have a 4-hour journal to minimize the storage needed for the journal. Zerto is a great disaster recovery solution, but not as great as a backup solution.  Many customers will augment Zerto with a backup solution for long-term retention of past data. Long-term retention is…

The Difference Between Disaster Recovery, Backup and Business Continuity

I sometimes see words like backup and disaster recovery used interchangeably, and sometimes in the wrong context. I see a customers asking for a DR solution when they need backup and DR. Some refer to it in the industry as BDR (Backup & Disaster Recovery). So what’s the difference? Why should you care? Disaster Recovery Disaster recovery is about restoring critical IT functions quickly after a disaster. Disasters can be small from a critical server…
