Should I use client/server software compression or hardware compression?
<thead> </thead>| no compression | client software compression | server software compression | hardware compression | ||
|---|---|---|---|---|---|
| cpu usage | low | high on client | high on server | low | |
| network usage between client and server | reduced | ||||
| holding disk usage | reduced | reduced | reduced = reduced I/O and space | ||
| backup time | increased | increased | increased = because of CPU overhead | ||
| transfer to device | reduced | reduced | reduced = reduced I/O | ||
| device space | reduced | reduced | reduced | reduced = use less space | |
| DAR recovery | unavailable | Unavailable | DAR = Fast restore of a single file in a large backup |
- Disk size have increase faster then cpu speed, so software compression is less effective than many years ago.
- Hardware compression is often better than software compression
- Your choice depend of the resource available
